I guess I should first mention that I am still undiagnosed. I´m quite sure I´m on the spectrum, my guess is residual AS. I just thought I should get that information out of the way, since I am about to answer your question.
For years I was a dancer- that was my special interest- and now I am a dance teacher. In my case, going into teaching was probably one of the easiest roles I ever slipped into...(well, after that first day when I freaked out because I noticed all those EYES staring at me)...however, as you plan to teach children with ASDs, that shouldn´t be a problem...
In any case, I enjoy teaching because I am teaching the next generation all about my special interest. I have trouble talking to people generally, but just get me in a class and I feel comfortable. It can be scary when you have a new class, but I´ve noticed, through experience, it always works somehow. I think also, because I was a student myself for so long, it was pretty easy to evolve into the role of teacher; it seemed pretty clear what it was I should do. It can be tiring too, as mentioned, so try not to overextend your schedule.
Wow, so you´re thinking about teaching children on the spectrum! What a great idea! I´d also like to do something like that, maybe someday...probably not teaching per se, I´ve just been wondering if there´s a way that I can help autistic children. I´m not sure how yet, hopefully I´ll figure that part out....
