I am working hard to fix the same problem, as it tends to be the worst part of my game, especially after something bad happens to my chip stack. Or I want to win the tournament in the first or second level, when as the saying goes "you can't win a poker tourney in the first few levels, but you can lose one." Just be patient, build up your stack by trying to get in on reasonably priced flops and making the best hand or get it all in pre if you find a really strong spot. Don't worry about raising the blinds until the middle of the tourney when they start to mean something. One of the keys for me is to have something else going on while playing the early stages of the tourney. That way I'm not as thirsty for action, happy to fold so I can get back to the other thing I am doing, whatever that may be. Also you don't want to be trying to play a style that you see on TV or that other people might think is good. The important thing is to figure what works best for you and allows you to CASH. As the tourney progresses it is critical to watch closely every hand and learn all you can about your opponents, and take notes so you build up a database of info. This is as important as anything as it will tell you which decisions are best, like who to steal from and which players only
raise with AA, KK or QQ, which allows you to call knowing if you can beat the few hands they would raise with you can win a huge pot, while the worst case scenario if you trust your information and have the discipline to fold A9 on a 9 high flop is you lose only what it costs to call. Another thing is not committing yourself to big pots when you are uncertain of where you stand. Don't start betting wildly because you raised the button with j10 and a jack comes. Try to keep pots small until you know you have the best hand, and don't be afraid to make a lot of small probing bets to figure out where you are as a way of avoiding big decisions with a lot of uncertainty.
