I was chatting with a coworker today about the cello (it's quite a conversation piece) and he something to the effect of "Once you're good, you're good for the rest of your life, so enjoy being bad now while you still can."
I was with him on the first part, but he lost me on enjoying being bad. I'm bad at plenty of things, but I wouldn't say I enjoy any of them. I try to stick to things I'm good at. That helps me avoid tantrums.
Here's a picture of me from rehearsal tonight:
That's my cello buddy Mathew on the right. I've gotten in the habit of dressing nicely on Wednesdays because I know I'll get my picture taken. :)
