Poker time to reall learn and stop winging it

So I just got knocked out of my 4th (or 5th) SCOOP event. Fairly decent sized buyins (ranging from $100 - $225). It also occurs to me I deposit a whole lot more than I withdraw from PS!! I think its time for me to recognize that Im not naturally an incredible poker player. I always considered myself a "good" player, but that has normally been when playing fairly weak players. Now, when I'm involved in this MTTs with loads of supernova players, I can see I'm outclassed. How do I go about unlearning the crap I've obviously picked up over the years and begin playing decent poker. Any suggestions appreciated.
