Selfdicipline and psychology

Hi, this is my first post here, so please don't flame me too much if this should have been posted in psychology [img]/images/graemlins/smile.gif[/img]

My question relates to the topic of this post. In poker, i believe, as in other aspects of life, your personality/type influences your action in a given situation in numerous ways.
A somewhat reserved/introvert person might be more inclined to play tight and an extrovert might play more argessive regardless if their overall skill level is the same.

This is of course just an assumption but i believe from especially (though limited) live experience that risk averse people in general play risk averse poker and vice versa. In the same way people deal with tilt, variance, boredom and bankroll management much differently.

My question is essentially if you have any experience in analysing your own personality traits that influence your game, and if any books poker related or not, have helped you maximize the positive traits of your personality while minimizing the negative ones?
