i mean guys dont get mad or anything, dont take this the wrong way. IMO i believe that if you win enough money to withdraw then you think your a lot better than you really are. You put up to high of expectations, and when you dont succeed, you look for someone, something to blame.
I started playing on the net about 6 years ago. and seriously during the first 5 years, anytime i cashed out, i was putting money right back in say a month or so later. And i thought the exact same thing. Well you know what happened, i got better. I play in 30 sngs a day, one day i might run horrible, the next day i might run great. So if i cash out and then run horrible i know that if i keep putting my money in ahead, tomorrow im gonna win it back plus some. The last time i deposited now was dec 07, i think i was about 1k in the hole on FT at the timenow i've turned it around 180*. Read the poker mindset, it'll help change your mind. And when you do change your mind, you'll become a far better player, and win much more money.
