For every new addition request mid-project, apply one rule: it enters in exchange for something leaving, or waits for the next release.

Repeat the same refusal in the same words calmly, no matter how the other person reshapes the pressure.

Say no in three sentences: thanks, refusal, closing — with no "sorry" or justification.

Memorize one 7-word refusal sentence and rehearse it until it emerges automatically under pressure.

Say "no, I can't" — complete sentence. No explanation, no apology.

Identify who is your mentor (teaches) vs sponsor (opens doors) — both crucial.

Before any project starts, write a one-page charter answering six core questions.
