Building a bankroll

[ConsciousOne]

So i have been playing on partypoker in 10/25 cent blinds. I usually deposit 50 and cash out 50 when i get to 100. Sometimes i will lose the 50 i deposit, but i have got up to 3 cash outs for 150$ profit in about a day before losing my buy in again. One of my biggest weakness's is I will tend to play on tilt after losing a big pot, and this is often how i lose my bank roll.
I'm tired of having to continually go to the bank to deposit money after i bust (I have a seperate bank account that i don't keep extra money in for depositing). I know a good idea would be to just let my bankroll grow more before cashing out. Doing this though would also leave me more vulnerable to tilting away more money.
I know my best option is probably to let my bankroll grow and learn to control my tilt, I just wanted to post my situation and get some feedback though.
