I come out a winner, but a small one... help?

[UATrewqaz]

I'm relatively "new" to poker, been playing seriously for about 9 months now. I've read alot of the major "important" books (TTOP, SSHE, WLLHE - jones).

Obviously I started out God awful but over the past 4 months I have won over $1500 playing low limit hold em on Party Poker (.5/1,1/2,2/4). I also fair pretty well in small buy in SNG NL tournies.

Anyway... i've played TONNNNNS of hands to win this money, I mean tons. My BB per 100 hand win rate is pretty sad, but at least enough to make me money, but my question is simple...

I obviously have leaks, alot of small ones, maybe a couple of big ones. What is the best way to identify these? I can never move up in limits as long as I am a bottom feeder pulling in a few bucks off of morons.

What is the decent new player's most frequent leaks?
