Shooting Star, I have done a lot of volunteer work with non-profits. I absolutely loved being on the board of the JCC in Tempe, AZ. I ran a few large events, in addition to teaching fitness classes (paid) there, while my kids went to preschool. Then, when I moved here, I threw myself into volunteering at my synagogue. Bleh. After the 1 millionth discussion of what we should serve at an event and dealing with people who had no clue, I stopped cold turkey... I even quit being president of the school board for religious school in the middle of the year as it was upsetting me so much.
My volunteering now consists of leading rides for the AMC and presenting at the Bike Workshop every spring. I really enjoy this, but I have cut down on the number of rides I lead. When it starts to feel like a job, it's too much. I wouldn't be adverse to doing different types of volunteering for them as I cut down my work even more.
