The quickest way to relieve stress from it? Conquer it. Find a way not too "care" so much about the result. Because guess what? No matter who good you'll be, you WILL get rejected from time to time. Learn to deal with that.
Be happy about the fact your own a great path to getting better results, that you're doing something about it. If we all worried about every little "ex" and "oh" then we'll beat the living shit out of ourselves every time a woman said no. Trust me my man, this all is NOT a big deal

People want success with women to fill other voids in their lives, not that they honestly want a woman for the rest of their lives. Or even just to get laid.
Either way, find your own reason for doing all of this and roll with it.
