Hold your position when movement would only satisfy nerves.

There is a kind of movement that exists only to discharge anxiety. It looks like progress, feels like relief, and changes nothing about your actual position except to spend something. Learning to recognize it is one of the more useful things you can do.

Before acting, ask whether this move improves your situation or only your feelings. If it is the second, find another way to settle yourself: walk, talk to someone, wait a day. Then decide again with a calmer hand.
