What are the most common leaks for a losing/break even player?

[ATM]

I play 6 max NL on pokerstars. I played $0.5/$0.10 but because of my bad play lately have tilted off a lot of my bankroll. I think I need to go down to $0.01/$0.02 I dont have any stats because I dont have poker tracker but while playing on Titan poker for 2.5 hours with a guy he gave me the stats i was running off of his poker office which were 35,3/11,18,2 and 28/17/1,6 (both separate occasions not sure what these mean though) but these probably dont help because it was only twice and I could have been running good etc. I'm bad for tilting and paying off the stations when they hit there draws and sometimes not sure how to discipline myself to stop calling there min bets when they hit there flushes and straights etc. I dont properly think through a hand while playing either. What should my thought process be for every hand?

My suggetion would be two things:

1. Get Poker Traker it is only $45 and worth the investment because if you use the information it provides about your game it will pay for itself in wins or at least by lessen your loses.

2. Get Dan Harrinton's books, good, conservative player with great Hand Problems in the books.

Both great ways to plug leaks in your game.

Good Luck
