Game Changes; Internet Tourney vs. Live ring

[DMP]

I do fairly well in STT SNG's (60% cash) but my live game is really off. I know that I'm doing something wrong, but I just can't put my finger on it. I'm not sure if I'm raising too much or letting hands go too early, but I don't know if there are any general playing changes you need to employ when switching over from internet tourneys to live games. I understand this is pretty vague, but I'm just looking for some general things to look for in my game.
