When there’s a gold rush, sell shovels and picks, a classic business and entrepreneurship quote with prospectors chasing gold and suppliers lining the road

When there's a gold rush, sell shovels

I love this age-old wisdom. It may be about the gold rush, but I see it everywhere to this day. When everyone is trying to get rich in the sensational way, the people who reliably do well are those who sell to the people trying to get rich. In the gold rush, prospectors and miners seeking their fortunes headed up to the hills to find gold. A few of them found it. But, like all get-rich-quick schemes, the vast majority of them found no gold claims that made their fortune. Whether they got lucky or not, they needed tools—shovels, picks, buckets, pans. They also might have purchased mules, food, lodging, supplies, guidance, and maybe they bought whiskey to drown their sorrows. Famously, they might have needed hardwearing work clothes, of which denim was the perfect solution. And the interesting thing about all the people who sold to the prospectors is that they could make money whether their customers found gold or not. They can sell to the people winning and the people losing. The saying has at least a few different forms: The secret to getting rich in a gold rush is selling picks. When Everybody Is Digging for Gold, It’s Good To Be in the Pick and Shovel Business Don’t dig for gold, sell shovels. Some Modern Examples Selling shovels in the gold rush is the classic example, but modern-day examples abound. It often looks like selling access, tools, platforms or advice to people chasing a quick buck. Investment brokers and platforms that charge for trading. Brokers and platforms make a profit when the market dives and when it soars. The more activity there is, the better they do. Exchanges and marketplaces. Where the trading happens, whether it’s stocks and shares, second-hand goods, or vintage furniture. Tooling and platforms. YouTube, AWS, Domain providers profit the more people try to seek their fortune. “How to make money doing X” courses and education. Looking to make money doing X? Buy the course, and you’ll get the exact steps to replicate the winning strategies. Earn on YouTube. Monetise your newsletter. Publish your book. And some slightly more oblique examples: Transformation industries. Gyms and supplements sell the promise of transformation, regardless of whether people achieve their goals. Self-help and productivity. Just implement this new productivity tip, and you’ll transform your prospects. In each case, millions of people purchase without achieving the ends they were hoping for. But the shovel-sellers do well either way. A Simple Formula It’s seductive because, in classic survivorship bias, we see the people who’ve made it: the YouTubers with millions of followers, the crypto early adopters who didn’t sell in a crash, the property flippers who bought at the right place and time. But sometimes the people doing best seem to be those promising to teach you how to get rich that way In most of these cases there’s: A new way of making money High-visibility successes A self-reinforcing loop: the more people follow or buy your course, program, or product promising success, the more successful you look, and the more legitimate your service seems. Try Selling Shovels I share this because I regularly reflect on it as a lens for my own activity. Am I trying to follow the herd and the gold rush? Maybe I would be better off helping others in their journey for gold? How could I support them instead of rushing myself? It’s tempting to imagine yourself as one of the winners of the gold rush. But all that activity creates opportunities to support the prospectors. Selling shovels means your future is less dependent on being lucky, early, or exceptional and hitting a gold seam. Or maybe I'm just jealous ;o) -- As usual, if you’re looking for the origins of the phrase selling shovels in a gold rush, Quote Investigator has done the work for you.

Front-load key words in lists and when writing for the web for clearer communication with a conference features example

Front-load Key Words

People don’t usually want to read online—they want to get something done. This means that when deciding whether a service is worth subscribing to, figuring out which plan is better, trying to understand a set of features, or determining whether you need this product or that, people mostly just want to skim through. So the easier you can make this for them as a writer and designer, the better. One simple tweak I use regularly when writing or editing is to front-load the meaningful words in lists. What Is Front-Loading Meaningful Words? Front-loading means placing the words that signal most—those that convey meaning or make the point—right at the start, not buried in the middle or end. I learned this lesson through many painful examples of people not reading what we’d written on a page and then complaining that we never told them. Here’s a list I worked on from the welcome email to the newsletter. This was my first draft: Explore the sketch archive on sketchplanations.com Dig in more with the Sketchplanations podcast. At 50+ episodes and counting. Fun, lighthearted and thought-provoking, my co-hosts and I take a sketch each week and dive in, sometimes with an expert guest to help us out. Prefer reading off devices? Me too. You can catch up on past sketches with my book Big Ideas Little Pictures Revision: More to explore 🔍 The full archive on sketchplanations.com 🎙️ Sketchplanations podcast—50+ lighthearted episodes diving into one sketch a week, often with expert guests 📔 Big Ideas Little Pictures—Prefer reading off devices? Me too. A collection of nearly 150 of my favourite sketches in a book (emojis optional, but in this case, they perhaps are an even better scanning tool. Or not.) Now, you may prefer the first one, but if you’re in a hurry or still undecided about whether this is worth reading, the second is more likely to convey the key points I wanted to share. No doubt more improvements are still possible. Because links have formatting that draws attention, it also helps to have each of those at the start, or at least in a consistent place, to aid scanning and skimming—as in the revision where your eyes can scan straight down the key information. This supports the F-Shaped Reading pattern, in which people often scan pages in an F shape. The revision is also shorter, so it’s more likely to be read. This is not a tip for writing novels. Nor, perhaps, for your email newsletter. But in situations where people are skimming—often not even sure they want to read your writing—it helps a lot. That includes almost everything on the web except long-form essays, but also plenty that’s off the web too: Safety notices Public transport information Shop signage Job descriptions Menus Instruction manuals Onboarding checklists Property listings Event schedules And more. Front-Loading to Refine your Link Text The same front-loading principle applies to the words you use within link text, for example, take this sentence and link: For another use case, see the F-Shaped Reading pattern For scanning, this is generally better as: For another use case, see the F-Shaped Reading pattern. ...because scanning the text of the link itself immediately tells me “F-Shaped Reading” rather than “see the...” Link text is one of those places I always want to improve. I made a ‘click here‘ category of sketches to get across this idea: Rewrite to avoid click here. For another post. When time is short, attention is limited, or people just want the next step. So, start with the most useful words.

Laplace's Demon thought experiment quote by Pierre-Simon Laplace about determinism and predictability

Laplace's Demon

For an all-seeing, all-knowing being, the future is as clear as the past Perhaps you, like me, have once considered a thought experiment: Given all the laws of nature and given the current state of everything in the universe, in principle, you could figure out exactly what was going to happen. The laws of nature would just keep things moving as expected, and events in the universe would unfold predictably and imperturbably. What about free will and all that? This idea of a being that knew all the laws and the current states of everything, and therefore how everything would play out, is called Laplace’s Demon. It was named after an extremely smart French mathematician and polymath, Pierre-Simon Laplace, who once wrote (translations vary a little): “We ought then to regard the present state of the universe as the effect of its anterior state and as the cause of the one which is to follow. Given for one instant an intelligence which could comprehend all the forces by which nature is animated and the respective situation of the beings who compose it—an intelligence sufficiently vast to submit these data to analysis—it would embrace in the same formula the movements of the greatest bodies of the universe and those of the lightest atom; for it, nothing would be uncertain and the future, as the past, would be present to its eyes.” — Pierre-Simon Laplace, A Philosophical Essay on Probabilities Determinism is the idea that everything is pre-determined and nothing is left to chance. Laplace’s Demon thought experiment represents the extreme side of that. There are a few challenges to this idea since then, including the practical unpredictability of chaotic systems, quantum mechanics, the difficulty of measuring without disturbing, as well as philosophical and religious ideas about free will. Even if the future did follow perfectly from the past, in practice we couldn’t work it out. Notes on Laplace’s Demon I learned about Laplace’s Demon in David Spiegelhalter’s The Art of Uncertainty after he joined us on the podcast about microlives. Laplace’s Demon is less well-known than Maxwell’s demon — a teeny being that appears to violate the second law of thermodynamics. More generally, Laplace’s Demon is a thought experiment—a hypothetical scenario that helps stress-test and illuminate ideas. Related Ideas to Laplace’s Demon Also see: Laplace’s Demon is an eponym Russell’s Teapot Chesterton’s Fence Black Swan events The Lucretius Problem Hanlon’s Razor The Monty Hall Problem More eponyms You can read a translation of Laplace’s words in his article A Philosophical Essay on Probabilities on Project Gutenberg (this appears near the beginning).

Common dune types showing how different wind patterns and sand availability shape transverse dunes, linear dunes, barchan dunes and star dunes.

Dune Types: Transverse, Linear, Barchan, Star Dunes

Sand dunes can be beautiful and awe-inspiring. And, though they come in infinite shapes and sizes, specific combinations of winds and sand together create common dune types. I find it interesting to try to recognise the basic types and why they form in the way they do. Here are some of the most common dune types. Transverse Dunes Transverse dunes form, somewhat counterintuitively for me, perpendicular to the wind direction. It’s rather like how a dirt road washboards perpendicular to the direction of traffic, and ripples on the beach will often form at right angles to the wash of the waves. When there’s plenty of sand and the wind is predominantly from one direction, sand begins to pile up and creates sheltered depressions on the other side of growing dunes. The sheltered zones help set up fairly consistent spacing between dunes. It’s fascinating to observe both at a tiny scale on the beach and flying over a vast desert. Transverse dunes typically have a shallower up slope in the direction the wind arrives from and a steeper slip slope on the sheltered side. I learned that the shallower upface is called the stoss side, and the steeper slipface is called the lee face. Linear Dunes When wind blows from two directions, dunes can be pulled into long, linear ridges, forming longitudinal dunes or linear dunes. The ridges align with the average direction of the wind. Some ridges can run for a hundred miles. In contrast to transverse dunes, wind from both directions creates slip faces on both sides, often forming sharp edges along the dune ridges. This leads to the more poetic name of seif dunes, meaning sword in Arabic. Barchan Dunes When the prevailing wind is from one direction and sand is less plentiful, crescent-shaped barchan dunes form. They have characteristic horns extending in the direction the wind blows. Sands are always shifting, and barchan dunes can move relatively quickly along the desert floor compared to other large dunes. Star Dunes When winds blow from many directions, sand can get blown into dunes that grow vertically in a star or pyramid shape. Remarkably, they can reach up to 500m tall. In some areas, star dunes form along longitudinal ridges. Other Dune Types The interactions of sand and wind are endlessly complex, and other types of dunes exist. These include: Dome dunes, without prominent ridges, as you might imagine Parabolic dunes, which look like barchan but face the opposite way. Look out for these near the coast. Reversing dunes, which have a sort of mini-dune facing the opposite way at the top of the ridge. Draas: mega-dunes sometimes made up of other dune forms.

What is contentment? Happiness, wellbeing and contentment is what you have relative to what you want, from Morgan Housel’s The Art of Spending Money.

Contentment: What you Have Relative to What you Want

Morgan Housel, in his book The Art of Spending Money, says that contentment is what you have relative to what you want. If you have money for a life full of comforts but envy a more glamorous one, you will make yourself unhappy. If you have a simple life with friends, family, health, and interests, and don’t want anything more, then you will be happy as you are. Money makes this visible, but the same rule applies to almost everything: time, relationships, status, health, and freedom. Being content with what you have is a counter to the hedonic treadmill: how people can easily get used to a better situation and start longing for the next thing (been on the list to sketch for a long time!). As Morgan says, “If your expectations grow faster than your income, you will never be happy with your money.” It’s funny how knowing that someone or something has something better can affect your own satisfaction with what you have. “If I hadn’t seen such riches, I could live with being poor.” — from Sit Down by James (video) I think about this song line quite often. One of my favourite perspective shifts on this is comedian Louis C.K.’s Everything is Amazing, and Nobody is Happy clip with Conan O’Brien. He captures brilliantly how quickly our sense of what is normal inflates, even as life objectively improves. Low expectations? In a class on utility theory long ago, I remember mathematically seeing that if you expect little value, then you’ll be satisfied with whatever you get. And I’ve heard it said that the secret to happiness is low expectations. There’s something in it for sure, but it always seems like a double-edged sword to me. Sure, if you expect your team to lose every time, you might not be bothered when they do. But if you hope that they’ll win, you can get some happiness from that excitement, too. It’s always intriguing how supporters of better teams get more frustrated when they do slightly worse than usual, even while they are still doing much better than my team. Expectations are tricky. It’s so easy to recalibrate what counts as normal. You can skip the ups and downs of supporting a team by not supporting one and not caring what happens. You avoid the downs, but you miss the ups, too. (see The Supporter’s Paradox in Big Ideas Little Pictures) The late Queen Elizabeth II said it beautifully: "Grief is the price we pay for love." — Queen Elizabeth II You can skip the grief by not loving, but that seems a shame. How life feels depends on what we expect as much as what we get. Related quotes "Annual income twenty pounds, annual expenditure nineteen nineteen and six , result happiness.

Explanation of SMART goals meaning, showing that SMART stands for Specific, Measurable, Achievable, Relevant and Time-bound, and how setting SMART goals leads to clearer progress

SMART Goals

If you’ve heard of one framework to help with goal-setting, it could well be this one: SMART Goals. SMART is an acronym to keep in mind a few ideas for setting better goals, ones you’re more likely to make progress on and complete. I’ve lost track of when I first learned it, and I do keep it in mind when I set goals. Running through as a little mental checklist helps me go from vague, easy-to-ignore goals to ones with more tangible progress. What are SMART Goals SMART stands for: Specific Avoid vague, fuzzy goals Measurable How will you see your progress, and when you’ve achieved it? Achievable Are you able to control and influence your progress? Relevant Is it really what will help you most? Time-Bound A timeline and deadline spur action I’ve seen some variation in the words, in particular with Achievable, Attainable, or Actionable, Relevant or Realistic, Time-Bound and Timely. Either way, the broad intent, as I understand it, is generally the same: turning vague, passive, and imagined goals into decisions, signals, and progress. SMART Goals help you go from something like: Next year I will get fit to: I will run three times a week, aiming for a 10k personal best in July I have found that if I do actually want to make progress and not just make the same goal next year, the second formulation here will help me. There are many goal-setting frameworks. And there’s advice to focus on habits and systems rather than goals (see, for example, Atomic Habits). SMART isn’t always the answer and at times other strategies might serve you better. Use what works for you. How I use SMART Goals I’ve definitely found SMART help me over the years. Here’s how I think about each of the aspects of SMART Goals: Specific Specific is better than vague. Just like breaking down a big project makes it easier to get started on, getting specific helps me focus on something I’m more likely to act on. Try more new foods, I find, is not as good as Cook one new meal a week. Getting specific forces you to think about how you will make progress on your goal. There are many different ways, and I sometimes find that I didn’t choose the right thing. No matter, just switch it up when you find what really helps you. See Implementation intentions. Measurable I have been involved in several projects at work where we made changes only to realise we had no way of knowing whether they improved things. Sometimes we hadn’t bothered to take a measurement before we started working on it. Other times, we hadn’t included a way to measure an outcome from the change we made. These projects weren’t very satisfying. Keeping your goals measurable helps you know if you’re making things better, and is more motivating along the way (see Flow). For example, measurable helps you go from "Improve the onboarding experience" to "Improve the satisfaction score post-onboarding by 50%." Or ”Get healthier” to “Lose 3 kilograms”. Sometimes changes in what you really care about may take time, and you may need to consider leading rather than lagging metrics. Achievable It’s miserable and demotivating working on goals you stand no chance of hitting. It’s great to think big (as in the BHAG: Big Hairy Audacious Goal) and, in my experience, it also helps to set goals that are hard but that you stand a chance of getting close to. I have spent a year or more working on company goals that no one really believed we had a chance to hit. Missing it every week is no fun. It’s not always easy to set a specific, measurable goal that’s achievable, usually because I don’t always have a good sense for what’s possible. Fortunately, goal-setting doesn’t have to be a one-time exercise. If you set something too high or too low because you didn’t know what was possible, readjust. And if nothing else, you’ll have made progress and be wiser. If your goal is to run a sub-3-hour marathon but you’ve never really run before, you might be better off starting with “Complete a half-marathon,” until you know how hard running a sub-3-hour marathon is (it’s very hard). Relevant The idea with Relevant goals is that they are the most important ones. It can require some thinking about what you really want to achieve. You don’t want to climb the wrong mountain. A little thought to check I’m really on the right path at the beginning is helpful. Time-Bound This is a reminder to me that a goal without an end is very easy to ignore. Setting a timeline and end date allows me to plan and forces me to make progress even when I don’t want to. Related Ideas to SMART Goals Apparently, as for productivity, I think about goal-setting a lot. Here are some other concepts that might help when setting or working on your SMART goals: The Fresh Start Effect (podcast episode) Leading and lagging metrics Implementation Intentions Clear is kind Local Optimisation The Power of Streaks The Doorstep Mile Enough molehills make a mountain The twin engines of Altruism and Ambition What Drives Us Everything is Aiming Replicate then Innovate Accuracy vs Precision Public Commitment Pledge Commitment Device Goodhart’s Law—very relevant if you’re setting goals for others What gets measured gets better Flow Find your why not
