You probably have a habit everyone notices and nobody mentions. Ask a close friend what it is.

Small habits are invisible from where you stand. The way you interrupt, a phrase you overuse, something you do with your hands when nervous: people register it immediately and say nothing, because mentioning it feels rude and the moment passes. So it carries on for years, known to everybody present except you.

Ask somebody who has known you a long time, and make it easy for them to answer honestly. Tell them you actually want to know and will not be strange about it. Then thank them, whatever it is, and decide later whether you care.
