Hi - I wasted some time thinking about what I had a passion for -then I just decided to focus on what was available and realtively inexpensive and might be fun. We are talking playing here, not career choices!
What you did with your kids is exactly the sort of thing I meant. What about drumming, or salsa, or learning Italian - NOT for a certificate, but for the sheer enjoyment of the playing.
Perhaps someting you wanted to do as a little kid and never did?
