Relax

People don’t often hear your mistakes, they hear the music, get the overall effect. Take a lesson from actors who perform “in the moment.” When performing for others you should never do-over a poorly played note. And when practicing you shouldn’t do-over either, or not often. If you stop every time you make a mistake, you’ll get in a bad habit of doing so, and you’ll stop-and-start when others are listening. Amateur actors correct mistakes they make speaking, pros behave as if they’d spoken correctly, and move on.
