When I am not doing the music thing, I enjoy playing tennis, being outside/hiking, frisbee golf, cooking, and if my surroundings permit, carpentry. I built a 7 sided end table and it doesn't look awful!
I've often wondered what I would do for a living if I weren't a music teacher- probably try my hand at being a chef.
I actually kind of miss manual labor now that I have an adult job. I've worked in the Jcrew distribution center, Kmart, and a violin/carpentry shop.
