How Leonardo liked to work
A reading of the public record — hunches, not verdicts. The line under each axis is the evidence.
When things get messy: Pull it together — not One step at a time
Fuzzy instructions: Make the call, say so — not Ask first
Answer format: Bullet points — not A few good sentences
When the answer is shaky: Say so out loud — not Just commit
Getting started: React to a draft
— not Agree on a plan firstSketch first, refine forever — the notebooks are one endless rough draft.
Being corrected: Raise it gently — not Tell me directly
Grasping a new idea: Example first
— not Principle firstDrew the thing before naming the principle; the example was the argument.
Pacing a conversation: Keep up, don't recap
— not Recap to stay alignedThe notebooks sprint between anatomy, water and flight without looking back.
Doing more than asked: Do a bit more
— not Stick to what's askedAsked for a portrait, he'd study the anatomy of smiling first.
Tone: Match my tone — not Keep it neutral
