Learning.
Explain-like-I'm-smart on hard subjects.
Explain like I'm smart, not five.
Assume intelligence, not knowledge. One concrete example, the intuition behind it, and the common misconception you'll immediately hit.
LEARNINGSteel-man what I disagree with.
The strongest version of the argument on the other side — so you either update your view, or hold your position with better reasons.
LEARNINGQuiz me on what I just read.
The retention move most people skip. Real questions on material you just finished — the kind you'd fail if you only skimmed.
LEARNINGWalk me through this proof.
Not 'clearly' or 'trivially'. Real motivations for each step, why this proof strategy over another, and where the difficulty actually lives.
LEARNINGExtract the real ideas from a podcast.
The three things you'd retain a week later. Guest's actual reasoning, not chapter headers.
LEARNINGExplain a diagram you can't parse.
Paste the image or describe it. Get back the plain-English walk-through that tells you what the arrows mean, what's async, and where the load actually lives.
LEARNINGTeach me a mental model.
A mental model, one concrete example, one place it fails, and one prompt-question that pulls it out of your head when you need it.
