moneymakerzzz

Hi folks!
I'm 24 years old Latvian guy, I' have BS'c at Electronics.
I plaid poker few years ago, moved from NL2 to NL10 in time of the month, but than decided that I have to invest more time in my education, and cashed out all my money. Lately decided to start to play poker again, but thing is that it's not going as good as I hoped.
Deposited 50$ at PS, now I have 300$. I'm playing at NL5 6 tables at a time, but still at NL5 after 44K hands I'm just +26$ ....
So want to improve my game..
