I like running sound... now what?

I'm a middle-school computer geek and a general intellectual, and somewhere around fourth grade this led me into audio. At that stage, it was just a CD player connected to an amp for an elementary school winter music concert, but I stuck with it. The next year, I ran a portable Yamaha mixing console under a district AV technician, and in Middle School I ran a full-fledged sound board myself in a pretty nice and well equipped auditorium for two talent shows. Next was a musical in our gym (our show was postponed and the aforementioned house was booked, so the school blew ~$6,000 renting sound and lighting systems) which went okay but we didn't have wireless mics, so there was a lot feedback from mics cranked up way too high because the performers didn't get close enough... anyway....

I loved every second of it. I don't know... there's something different about running a live show, a dynamic quality writing short stories and software just doesn't have. That, plus it was a complex technological system to be figured out. Right up my alley...

So my question is this: knowing I enjoy this kind of thing, what can I do with it, other than jump at every opportunity to run sound for my school? How can I do this kind of thing more often? (Our school has 2, maybe 3 shows a year, that's it.)

Also looking for informational resources, books, etc...

I don't want to pursue this kind of thing as a career, not like software engineering, but I do want to do learn as much as I can and do it more often.

13 here, with most of the financial limitations that come with it. I do, though, have a Macbook Pro and studio monitor headphones (UE Pro 5s). No, I don't really play an instrument; I play the trumpet, but not enthusiastically (in fact I only stick with it because I can't bear to quit).
