I'm gonna have to state the obvious & say work on your tilting. If you go ape-$hit everytime your aces get cracked (whcih they will regularly on 1-2 PP games), you are going to have many headaches to come. Apparently tilting less is a skill you aquire over time (i dont have it) ... but I would say just be careful & play within your means ... your described history seems very gamble-happy.

In terms of your game itself - it seems you are doin the right things, reading posting, playing etc.
