I should probably expand on this a bit:
From what I've seen and experienced, a lot of guys are pretty rigid in their self-image. When I go out to the bars and clubs, you can see the dudes that are all caught up in their ego and self-image.
These are the guys that are hanging out in the corners standing with their chests puffed out exaggeratedly with their drinks to their chest, trying to stand taller than they really are (random question: has anyone else noticed a high concentration of short guys in bars/clubs? Seems to be the way it is here in Denver), you know, trying to look cool/hard and basically just posturing. Then one of em goes up, opens a chick, gets blown out, turns red, and goes back to his crew of ball lickers.
Yeah, don't be that guy. Be flexible in what you expect of yourself, and understand that so many parts of life and the game are entirely subjective, just products of electric impulses and brain chemicals and social programming and social dynamics.
1.) Don't confuse who you ARE with who you are percieved to be by others
2.) Don't take things too seriously. If some chickie is indifferent to you, suck it up. Don't take it personally.
I guess that's all I have to say about that.
