Every time you wait instead of reacting, future you avoids one more mess to clean up.

Most of the cleaning up people do is for things they said in the first ten seconds. A reaction is cheap to produce and expensive to undo, and the distance between those two prices is where all the apologies live. Every pause you manage is a mess that simply never happens, which is why nobody ever credits you for it.

Build one deliberate delay into your week: no replies to anything that stings until you have walked away and come back. Draft the furious message somewhere it cannot be sent. Keep a count of what you did not have to repair.
