There is some sound advice here that is worth considering and looking up.
personally i dont think you playing the live game enough. Id raise a lot more hands live than i would online. Im talking suited connectors, any ace. While there are still ten players yes this is risky but as the field starts to thin its definatly the way forward. Also, live i do less calling im either raising, reraising or folding (perhaps wathcing some tv poker will help here, especially some short handed tourney games will help. They raise big any ace any pp and in mp/lp any two face cards, most fold these to any reraise or push unless they think they are infront (you need good reading skills here))
Somebody said you probably have a passive style and this may be the case. If i was in your shoes i'd be tempted to bust out a few times over the next few weeks on dangerous plays eg pushing your pp over the top of someones raise a few times.
But overall loosen up by raising or folding no limping unless the whole damn table is limping and when you raise raise like you have the nuts but know when to rep and when to fold to reraises or shows of strength.
good luck, hope my style will help with your problem
oh yeah and be confident and aggressive
