Losing well, and when to stop

Sometimes you make the case properly and the decision goes the other way. Say clearly that you have said your piece and you are behind the outcome — and then be behind it. The person who argues hard and then commits is trusted with the next argument. The person who keeps relitigating is not.

And know when a disagreement is not worth having at all. Not everything needs resolving, and a reputation for judgement comes as much from what you let go as from what you contest. Spend it on the things where being wrong actually costs something.
