Music is a perfect image of life. Each measure, each beat, each part of each beat represents a fresh beginning. The same "you" who played that note wrong yesterday or two minutes ago no longer exists, but is replaced by a new "you" who will play that note differently because charged with new energy, new vitality.

No wonder musicians come into our own in our 60's and really get steaming in our 80's. No wonder many great artists are still performing at 100.

You could look it up.
