If the question is "Is Poker profitable long term." I say just as much as opening a high risk business like a Bar or Restaurant. In today's game, the idea is. If you are playing perfect poker, and never make a mistake there is still a 30% chance you will be a losing player. More mistakes you make, the higher that number goes up. once you break 50% you have a better chance of losing money then actually making money long term....
If this is know you need to go in with 2 mindsets.....
1) I'm gonna play for fun, learn on my own, not commit a whole lot of time, and just treat it as a hobby to pass time. If I win, I win. If I lose, I lose. Im not gonna lose sleep over it.
2) Im gonna be a winning player, possibly go pro, and do this for a living. If that's the case you have to not only commit to studying your game off the table, but you need to know how to study. you have to understand GTO, ICM, True and Fold
equity. know how to take notes.... without these things your gonna fail....
At the end of the day, if you want to be profitable you have to treat it like a business. set a schedule, study, always view every play as an investment. All while knowing when you can take down a pot with a strong
bluff... And always knowing even if you do all the right things there is still a 30% you will fail....
So the choice is up to you. Is it worth the effort? Only you can deside.
