get at least 30k hands and then post a picture of your stats from your tracking software. there are a million other stat threads which you can study to find out what kind of info has been beneficial for spotting leaks.

from what little info you've provided, i'd guess you're playing far too many hands out of the blinds. particularly the SB (you always get better pot odds to call or 3b in the BB so your range there should be slightly wider than SB)
