Congrats on your current bankroll. Even still, at $150 you are not rolled to play the stakes you are playing. Enjoy this rush while it lasts, because sooner or later a cruel mistress named Variance (has a ring to it, no?) will rear her ugly head and leave you penniless.
At this point, you are not really playing poker, it more resembles bingo than anything else. I'm not saying it cannot be done, I'm sure plenty of people have deposited $20, taken to the .50/100 table, ran it up $500 and started their rolls that way. It even has a certain appeal to it than constantly grinding the micros.
If you do happen to build a roll and stay at current stakes, then bravo. But if you attempt to move up in stakes after you amass some cash you will be crushed. That was my whole point.
Pros preach Bank Roll Management more than anything, because playing over you limits is just plain dumb. Sooner or later you will end up in a big pot and someone will suck out on you. This is a fact.
But hey, what do the pros know? When's the last time they won a WSOP
Main Event right?
