Everyone has a blind spot. The dangerous ones belong to people sure they don’t.

A blind spot is not a flaw you refuse to admit, it is something you genuinely cannot see from where you stand. Everybody has them, which is ordinary and fixable with a mirror or a friend. The risk doubles for anyone convinced they have none, because certainty removes the reason to check. Being sure you see everything is itself the thing you cannot see.

Assume there is at least one habit of yours that bothers people who have not told you. Ask someone you trust what it might be, and let them finish before you respond. You do not have to agree today, just keep the answer somewhere.
