You can dream and hope to win money, or you can study, discuss in some comunities, see videos of the pokers, and be one of the best players!
Sometimes i see a lot of players overbetting the pot in the flop, players for example you want to buy a car it's 12k, u go to buy it and say i will give 16k for the car, poker is the same thing, we want the pot, but don't put more money than the pot size!
I personally like one comentary of one member of cardschats, PapaC
"If you believe you can, then you sure can, but if you believe you can't, then you sure can't." Awesome words for all players!
