Write it three times

Nobody believes the three-sentence summary is the hardest part of the day until they try it. You just read thirty minutes of clear, well-ordered explanation. Surely three sentences is a rounding error?

Sentence one exposes that you don’t know where to start. Sentence two exposes that the word you’ve been using all week — runtime, request, render — is a fog, not a concept. Sentence three is when you quietly go back and reread the middle section, and come back with something shorter and truer.

This is not a bug in your brain. It’s the method. Richard Feynman’s famous technique — explain it to a child, find where you stumble, go back to the book — isn’t about teaching children. It’s about finding the seams where reciting ends and knowing hasn’t begun. Writing is the cheapest child you have on hand: it can’t nod politely at a vague sentence.

So the loop here is deliberately small: read, explain out loud, write three sentences, mark it done. Not because the sentences are precious — you can delete them tomorrow — but because the person who writes them is a different person than the one who only scrolled.

Three sentences a day for six months is a notebook you’d never sell.
