use a strict BRM, know the value of a dollar just becasue your playing online it still is real money, people tend to forget that. Make sure you have 20 buyin's before you play MTT or cash game. Good Luck.
That isn't very strict at all. Some people say at least 100 buying for MTT... 50 FOR SNG... and minimum of 20 max buyin (100 big blind) for cash... and this is only if your a consistent winner.
