Okay, this is probably going to sound silly, but... I get the impression you know a bunch of things about a bunch of subjects. Any chance you could teach community college classes? On Egypt, travel, autism, taxes, all of the above? Contact with people is relatively one-sided as they're mostly busy listening to you, so not as much interaction as one might think...
I won a photography class and last year we hit the city of Amersfoort with the teacher, a professional photographer. It was nuts, and I did have one single panicattack, (Just one! And everyone was really nice about it too...!) but the results.... I think they were probably the best pics I've ever taken, streetphotography-wise. I had the least technical knowledge of the class at that moment, (which teach fixed as well), but the teacher, during the evaluation, gave me the best scores. By far. Said I had a professional's eye for it. Still makes me blush to think about it, but while it made me really uncomfortable, it also made me... I dunno... proud, I guess? Which I'm not used to being of myself.. It gave me such a boost, and it made quite a difference for me. And I've invested in a second camera, it came in today.... So I'm back to carrying around two of them. (I used to, but the ones I had were too heavy for my back. System camera's are lighter. Anyway....). You don't need teacher qualifications to do it far as I know, and I do think you have enough to share... It is a chance to make a difference, sharing what you know, and making a decent extra buck for traveling/a bit of freedom. IF, of course, that is something you'd want to persue.
Just something I thought about over dinner. Probably absolutely useless, because I don't know what your limitations are, but... The classes or lectures on ancient Egypt I'd certainly like to take myself. looking forward to more blogs, in any case.
