Relaxation, acceptance, and ...

Relaxation, acceptance, and keeping open mind are key. First of all, peak performance isn't possible if one is not relaxed, and if one is going to stay relaxed they must simply accept problems when they arise and decide to solve them. If I can't do a move I merely accept that I haven't discovered the right sequence, instead of trying the same sequence over and over or just quitting. I will try to do it 20 or 30 different ways, making subtle changes in body position and fot placement, until I find something that does work. That's what I mean by keeping an open mind.
