Hi Adso,
My partner is 42 and we have recently realised that he has AS. He's always had the same problems as you with work.
Since he realised that he's an Aspie he quit his stressful driving job, and took a drop in pay to work part time with trees at a nursery. The best part is he has no problem with the social side as the people he works with are very chilled and good natured. Nobody thinks he's a smart a** when he makes suggestions on bringing in more walk-in trade, or rattles off the latin names of whatever he's planting. The environment is beautiful, peaceful & quiet.
The thing that I've noticed is, he's realised that his AS has been holding him back all his life and now he knows why he's accepted his limits. He knows he's smart enough to be a physicist but when he was at school they assumed he wasn't capable of college. At this point in his life I think the most important thing is that he doesn't dread each day. He's a totally different person than he used to be-I can't remember the last time he had a meltdown and I'm not walking on eggshells at home any more.
It may not be possible to find well paid employment in an area of interest for a lot of Aspies. My partner has always enjoyed plants, but has always thought that as he's capable of doing 'thinking' jobs he should be using his abilities to make a living. He liked driving, (just him and the radio) but it was the deadlines and interaction with stressed out people that ruined it, and carried on ruining his evenings & weekends cos he knew there was more of it to come. Not to mention the outraged reactions when he delivered to warehouses and shared his thoughts on the most efficient way to run them! (Well I was just being helpful, they're obviously wasting money doing it that way...)
I'm rambling but my point is that the way you earn a living doesn't have to be the best use of your intellectual ability. Maybe those kinds of jobs are just too stressful. Do a simple job with no more social interaction than you can cope with, and you won't be too emotionally drained at the end of the day to enjoy your obsessions!
