I think it's the only way i've been able to become good at a few things. I am full blown spectrum. My wife calls me Sheldon Cooper. I would say my son is too, but he doesn't have the extreme personality traights of the tism
i think the champions made a commitment to be the best at a sport and were willing to do anything to make that happen.
so all the hours of practice and playing /sacrificing for that one goal and talent is what got them there
if extreme commitment to one thing above all others you want to call ocd thats your call
i also think they try to be the best not perfect
