Money Withdrawal Strategy

[johnnyrocket]

I have been playing for a few years now. I am a winning player at various different games. With my BB/100 and such I have averaged about 300-600 income a week. I am a college student and like to build my roll but also want some money to show for my play.

I was wondering what strategies people use for withdrawing, but letting your bankroll grow for future play.

I believe Taylor Caby recommended withdrawing 1/3 of your expected winnings weekly. I like this style, was wondering what others do for this...
