I think that every guy has had that feeling - almost like being possessed - where you just can't seem to control your emotions, or your own behavior.
You know what you SHOULD be doing, but when you try to do it, there's this invisible force that stops you. I had a bad temper, and I could barely control myself when I was around an attractive girl.
I would start acting up - just like a little bratty kid.
I could even SEE myself doing it, and KNOWING that it was killing my chances with this girl... And then I went on this massive inner game "quest" I guess you could call it.
Women want it from us, and guys spend most of their lives working on feeling it and showing it.
