When I first got into pickup it was all about MLTRs and getting threesomes. Now not quite so bothered. I have a great girl and I don't really want to change that right now. Sure there are always other women I want, but I have not met any that can offer me anything more than I have.
It is always important to be aware of what you are going for. This will change all the time! You have to keep asking yourself if you are happy with your situation. It may be that the girl of your dreams turns out to be very stressful. Likewise keeping several women on the go may turn out to be very fulfilling and it could turn out to be a series of shouting matches.
In NLP they teach you to always visualise your desired outcome. Good advice. You will never achieve your goals if you do not have any.
I set my goal like this: I will never go for more than 1 month without getting laid again.
I have not missed a week since I set that goal.
As Asian Playboy says, Know Thyself. I think this is very profound advice, more than he goes into in that post anyway. I'll write more on it some other time.
You got into pickup because there was an aspect of your life you were not happy with. Always remember that it is your happiness that you are trying to achieve. If you are truly happy nothing else matters. This is your true endgame....getting what you want socially definitely helps though.
