Poker is a lot more about just being good, or at the pros level. Its about having good money management, always playing to your fullest potential and not going on tilt, not being results oriented and understanding sometimes when things do not turn in your favor that it not necessarily the wrong play, and making sure that what you are doing is something you really enjoy, whereas it isn't something that causes you more stress than income and enjoyment. It definitely isn't for everyone to take up super seriously, but if you got the game and you can tame out your side that wants to overly-gamble and lose composure, along with your bankroll, then it should prove to be an enjoyable experience.
