Learn to box. Not karate. Not chink bullshit. Boxing.
You learn how to fight which is good, you learn confidence because now if something goes south you can just beat the shit out of anyone.
Seriously. You'd be surprised how much of an edge on fighting it gives you. If your opponent doesn't know how to fight, which they most likely won't, you're going to win.
Russian Sambo wrestling also works well for this too.
