You don't consider it gambling? That's probably your first mistake. People who consistently win at poker (which is gambling BTW) are good at several skills including psychology, reading body language, mentally keeping track of cards & odds, and bluffing. Knowing when to "hold 'em" and when to "fold 'em" doesn't hurt either.
If you're going to gamble (poker is gambling) you have to be mentally and financially prepared to lose and not whine about it. Don't play with more than you can afford to lose. Don't spend the rent, grocery money, or college fund on poker.
Did I mention that poker is gambling? People would be playing it in church basements, instead of Bingo, if it wasn't.
