Being around a couple different pimps this weekend showed me what I believe is the number one reason why your game works for you. There are many principles that make it more effective, however, I believe it works simply because you believe it will. A lot of my game is inner game, with paradox and self fulfilling prophecy built in to my belief system. So I believe that this is a very key principle. Find even the most irrational factors to feed this belief, because it's an important one.
Caveat: Just because I feel a certain way about my journey doesn't mean you should feel the same about yours.
If you can't say that you would rather die than not do it; you don't want it bad enough.
