When I was a kid, about 10 years old, I made a conscious decision to stop being the weird kid. I didn't know why I was weird - in those days, autism was only for non-verbal kids who rocked in the corner.
I did it. Today, as long as I am not too tired or overwhelmed, I can imitate NTs so well, that they sometimes joke to me about other ASD people, thinking I'll enjoy it.
It took me 20 years, sapped all my energy, and looking back, I wouldn't have bothered. A little camouflage is useful, but mostly it wasn't time well spent. I mainly did it because childhood is hell for us, but childhood ends.
The fact is, I really don't like most NTs, and I really don't care what they think about me anymore.
If you do want to take that path, I'd suggest studying acting, and reading lots of fiction - anything except sf and fantasy. Those are written by us, for us, and have nothing to teach us about NTs. General fiction is THE storehouse of information about the ideal ways to behave, or to avoid behaving.
Acting is the big shortcut. It's what you want to do anyway. Pick a detailed NT character and play that part. Seriously, take classes, audition for community theater. And theater people tend to have so many issues themselves, that they may not even notice yours.
Don't bother studying psychology. I wasted a lot of time that way. It wasn't all crap, but acting and reading were far superior.
The best plan, if I had to do it over again, would be to put less effort into it. Just get good enough to not stick out too much. And find something better to do.
Either way, good luck.
