Your ego gets loudest when you’re insecure. Quiet people who know themselves don’t need the volume.

Loudness about yourself is usually a sign of a question that has not been settled. When you are genuinely okay with something it needs no defending, so you can let a comment pass without correcting it. The bragging, the over explaining, the quick anger at being wrong all point at the same place. They are not confidence, they are maintenance.

Notice the topic where you get defensive fastest, because that is the one still open. You do not need to fix it this week. Just stop reading the volume as proof you are right.
