This gets asked a lot on Poker forums and professional Poker players probably get to answer this all the time. There is no simple ‘yes’ or ‘no’ answer. It depends on how good you are, for one thing. You have to practice all the time, read strategy books, watch game and craft your strategy. You also need an instinct for reading people – this is harder to hone than strategy because you have to play a lot, watch other players and learn to read them over time. The hard leap for many would-be pro players is the jump between treating Poker like a hobby and treating it like a serious career. It means putting all those extra hours, and you may find you no longer enjoy it.
The next thing to consider is whether you can handle the pressure of a Poker career. Careful money management skills are imperative, as is the ability to know when to take risks. No one wins all the time, no matter how good a player they are, and you have to be prepared to lose as well as win. Professional Poker is a high-pressure job and you have to be able to cope with it and switch of the outside world while you play.
