I had a good day, today. I rode my bike about 1/2 as far as usual, and I don't feel absolutely whacked! I'm doing a "between bands set" Saturday night - about 20 minutes.
I've decided Small is Good. I can't do whole 2 hour shows any more, so I'm going to concentrate on open mics (10 - 15 minute sets), and opening for larger acts. I can still sell my CDs at these short sets, and I can still present what I compose ('cause I'll never stop that). Music is meant to be shared. I figure if I ever get to the point where I can't perform at all, I can ask my guitar buddies to play my tunes. They'd probably do it!
Small rides, small sets, small duration Yoga poses...it's all good.
Cheers,
