I feel your pain. I volunteered for my local fire department, and too late found out that they say, "You only volunteer once, when you fill out the application. After that, it's a duty." That turned into a second career, but I wouldn't have had it any other way. Volunteering is a very fulfilling part of my life, and judging by the responses above, I'm not alone.

I had to learn how to turn off the radio and take some time off. You have to find a balance, and that's different for everyone. Good luck--it's a nice problem to have, isn't it?
