Speak when you are angry and you will make the best speech you will ever regret.

Anger makes you fluent. Words arrive faster, phrasing sharpens, and every argument lines up neatly on your side, which is exactly why the result is so quotable and so expensive. What feels like clarity in the moment is mostly momentum, and it aims at the person rather than the problem.

Give your sharpest sentence a delay of one day before it gets spoken. Write it down if that helps, then read it back once the heat has gone. Occasionally it survives the wait, and then you can say it properly.
