Learn one hard idea properly in an hour
Builds a one-hour path through a concept you keep bouncing off: the minimum prerequisite, the idea itself, the two places your intuition will be wrong, and a test.
Four prompts for understanding something properly rather than recognising it — for students, for anyone onboarding into a new field, and for explaining it once you do.
A sequenced stack — each prompt is meant to feed the next.
How to use it
The order matters. Learn one hard idea is for the concept you keep bouncing off — it goes concrete before abstract and names the two places your intuition will be wrong. Active recall is for material you have already met and think you know; the "fragile" list it produces is the actual study plan.
Reading a paper is the one students and professionals both underuse: the gap between what a study measured and what its headline claims is where nearly all misreading happens.
Finish with explain it to someone who isn't an expert. Being able to explain it to a named person, without a false analogy, is the only reliable test that you understood it.
The stack
Work top to bottom. Copy a prompt, run it, then carry what you learned into the next.

Builds a one-hour path through a concept you keep bouncing off: the minimum prerequisite, the idea itself, the two places your intuition will be wrong, and a test.
Turns your messy notes into a testing session rather than a summary — it quizzes you, marks you honestly, and tells you which parts you only think you know.
Extracts what a study actually established, at what sample size, under what conditions — and separates the authors' claims from what the press release said.
Rewrites a technical explanation for a specific real person, keeps every fact intact, and flags where the simplification starts to become wrong.

Six prompts covering what a marketing team actually ships in a week — positioning, the landing page, the deck, the leave-behind one-pager, outreach, and social that isn't about nothing.
The four prompts for the part of job hunting that is actually work: making a résumé match one posting, writing a letter that couldn't be sent to anyone else, and walking in prepared.
For the management work nobody trains you for — giving feedback that lands, cutting scope when the date won't move, and writing the update people actually read.
