The one best answer is "It Depends".
Which aspect of your autism is the least troublesome for you?
* Little or no problem interacting with others? Try retail sales, teaching, call-centers, day-care, et cetera.
* Language skills okay? Journalism, writing, clerical, et cetera.
* Hyperlexia? Library, research, legal,
Focus on the strengths that autism gives you, and see where they might work best.
