Need help with bankroll management.

[Jesspoacher]

Two times this has happened now. I am not bad at ALL. I have rolled up 16k from 50 dollars a year and a half ago. After three days I went bust. And then just recently I rolled up 1k with 10 dollars. Again, went bust. I was playing where I shouldn't have been both times and I know this but it is hard to fight the urge to player low. Is there anything I could do to help me build patience? I want to get a bankroll were I can play 10/20 or 15/30 without having to worry.
