How do i know if i have asperger's?

See a professional: One should get a consult with a local psychologist or psychiatrist to decide on the diagnosis. It could be another diagnosis.

It's moot today: Asperger's is being dropped as a diagnosis among most mainstream physicians. The focused mind's a gift if wisely used. The real question is whether you can learn to do something that's harder for you than most other people -- read other folks, relate to them, interact more easily and naturally. This can be taught by today's methods -- and who wants a diagnosis of a mental illness?
