Activation Energy: Favourable Is Not the Same as Likely
Paper on a table will not burn, though burning releases energy. Something has to supply the initial push — and most stalled intentions are barriers, not disagreements about value.

The same behaviour gets explained by character in others and by circumstance in yourself. The asymmetry is not mainly self-flattery — it is what you can and cannot see.
An org chart looks like a diagram of authority. It works as a map of which conversations are cheap — and that is what ends up shaping the product.
The fossil record shows long stretches where species barely change, then rapid shifts. The interesting question is not why change happens in bursts — it is what holds things still for so long.
You can recognise thousands of faces and actively maintain far fewer relationships. The famous figure of 150 is contested — the underlying constraint is not.
Around thirty per cent of numbers in real datasets begin with 1, and only five per cent with 9. People inventing figures don't reproduce that — which is how the pattern became an auditing tool.
A treatment beats its rival for small stones, beats it for large stones, and loses when you combine the patients. Nothing was miscalculated — which is what makes it worth understanding.
The obvious response to a slipping deadline is more people. Output falls first, because the only people who can train them are the ones already behind — and coordination grows with the square of the team.
Most engineering time goes on code that already exists. Once you accept that, the practices that look like fussiness turn out to be straightforward economics.
Checking a tyre's pressure lets out a little air, so the reading is never quite what was there before. With objects that hardly matters. With people it can be larger than what you were trying to measure.
A few pea pods produced most of Pareto's peas. The lopsidedness he kept finding everywhere contradicts a default we apply constantly — treating twenty tasks as twenty roughly equal things.
Holding out two weeks for a better house price is worth a fortune to you and pocket change to your agent. No dishonesty required — just a small gap between what you want and what they're paid for.
The meeting you weren't invited to has two explanations that fit equally well. Preferring the boring one isn't generosity — it's what happens when you count how much each explanation assumes.
We label parcels 'fragile' but have no word for the opposite — not strong, which survives shocks unchanged, but something that improves because of them. Your muscles are the everyday example.
Colonial Hanoi paid a bounty per rat tail and got a rat-farming industry. The failure needs no dishonesty — only a proxy, a consequence, and someone rational enough to notice the shortcut.
A shower with a four-second lag will defeat anyone. The oscillation is a property of the loop, not the person — and most organisational dysfunction works exactly the same way.
A factory running at 98% capacity can still fail to deliver. Optimising everything except the bottleneck is not progress — it is an expensive illusion.
Assign four teams to build a compiler and you get a four-pass compiler. The seams in any system fall exactly where the seams between its builders already were — and rewrites that ignore this get undone.
A bicycle left in a field rusts; a rusted bicycle never un-rusts. That asymmetry governs warehouses, codebases, and institutions just as strictly as it governs steel.
Two petrol stations cut prices until neither can move without losing. Nobody wanted the result, everyone behaved sensibly, and it held anyway — because stable and good are different properties.
A map showing everything would be the size of the city and useless. Models work by discarding detail — the error is forgetting which detail, and when you left the range where it didn't matter.
Ask how to be a good manager and you get admirable vagueness. Ask what would make you a terrible one and the answers are specific, short, and something you can act on tomorrow.
Praise a great performance and the next is worse; criticise a bad one and the next improves. A flight instructor learned this lesson over years of observation — and it was never about motivation.
A two-page report takes a week if you have a week and a month if you have a month, and comes out about the same. Where the extra time goes is more interesting than the fact that it vanishes.
Cunningham's metaphor was never about bad code. It was about a rational trade — ship now, pay interest later — and the interest is levied on every future change you make.
