Most dancers find their confidence in dancing. Right is mere millimeters away from wrong. Failure is always louder than success. But there is an accumulation of all the things you don’t do wrong, and it becomes your confidence. You can even get to the point where confidence lasts longer than the dance. Seconds at first. Then minutes. Then maybe it’ll be there when you’re walking into a party, or meeting people after a show. You know you have something desirable, and you know you can move.
