I think there is a place to have mistakes and not have a chance for a do-over. I very much like the idea of making a mistake and not being able to take it back. I've been waiting until the next day for a second attempt, to see if I can redeem myself and avoid the mistake from the previous day.
Redeem, avoid? The mistake is a lesson not to be avoided. Enjoying doing things that you want to avoid later...perhaps you haven't really played music with other people who listen to you much. This is fine at home I suppose, but enjoying making mistakes is surely going to come through on the bandstand..
