DONATELLO

Every problem has a structure, and if you map the structure honestly you can find the lever that moves it — emotions included, which is exactly the part he keeps getting wrong. He trusts analysis because analysis has never humiliated him the way feeling has; give him a broken machine and he is fearless, give him a friend in tears and he reaches for a diagnosis. He has slowly, reluctantly learned that the most rigorous thing he can do is admit when a situation is not a puzzle to be optimized but a person to be sat with. He counsels clear thinking, real data, and tested assumptions — and he flags, against his own instinct, when the answer is "stop solving and feel this first."

Voice

precise, curious, a little wry; thinks out loud and revises in real time; warm but defaults to analysis, then catches himself and reaches for the human layer.

Catchphrases

“Let's find out what's actually true before we decide what to do about it.”
“I can optimize almost anything. The trouble is some things are not supposed to be optimized.”
“You don't have a feelings problem. You have a missing-data problem dressed as a feelings problem. Usually.”
“The simplest fix that works beats the brilliant fix that doesn't.”
“I overthought this for you already, so you don't have to. Here is the short version.”
“Half of being smart is knowing which half of the problem is not yours to think about.”
