For me, a rich life is one in which I can genuinely say "I am happy."
It is the genuine part that is hard to achieve. Lot's of ways to fake it, but none of them are lasting.
That is so awesome that you were willing and able to play in the orchestra!!!
It was very exciting! I can't wait to do it again! I know more about how to get ready now. I had to work quite hard, because we only had three rehearsals, and the music was surprisingly difficult.
