My favorite language for maintainability is Python. It has simple, clean syntax, object encapsulation, good library support, and optional named parameters.
When I put my mind to it I can be a megalomaniac.
My father taught me Basic and rudimentary C, I learned everything else on my own, including studying computational complexity on my own. That's more a function of my age than anything else though - back when I was in school there were hardly any programming classes.
In terms of work I've always had a Bad Attitude in that I won't work anywhere which requires me to work strict hours or follow a dress code. I don't know if that's an Asperger's thing or not, I think it's just being reasonable.
