Some of your best decisions are sitting unsent in your drafts.

Not sending is a real choice with real results, even though it leaves no evidence and earns no credit. The message you did not fire off at midnight saved a friendship that never knew it was at risk, and nobody will ever thank you for it. That is the nature of the good ones; they show up as things that did not happen.

When you write something heated, put it down and read it again in the morning. Ask what it is for, and whether the point survives being said calmly. Often the writing was the useful part and the sending was not.
