I wish I had dedicated myself to the game when I was much younger, when promotions were better and the players were much worse. These days I do not have the time or the funds to really invest in make a living from poker as I have a family to provide for. I have made an average of about $500 a year playing poker and that includes 4 years of being a losing player, but that is obviously not enough to live off.
As someone already mentioned, lots of players think that they can earn their fortunes from playing freerolls and never really getting any skin in the game. Invariably they win a couple of Dollars then lose it again very quickly few make it into double figures maybe a handful make it to $100, but then they either lose patience because it's take so long or they lose it all again.
People think that poker is a get rich quick game, the truth is that it is anything but.
