I encountered some of the same when I did community theatre. When I first started with the community theatre, I was in high school, and truly didn't know what was expected of me as an SM. I learned as I went. I read an awful lot and SMed for the high school and community college. The second summer I took on more. As I started college, I took on more. After the summer following my sophomore year, I decided that I'd outgrown community theatre. I'd accomplished as much change as they were willing to accept, but a lot of that, I found was due to a lack of interest in that particular theatre. Whereas first summer I was just there while my board ops took their own cues, the last summer I did it, I was op-ing both. Though I must say, given the choice between one or the other, I'd rather op both.
