As others have said already, the main cure is to become more aggressive, when blinds start to go up, and not be afraid to die. Look for spots, where you can put all your chips in the middle and give your opponents a tough decision, for instance by rejamming light. Rejamming means, that someone have opened the pot, maybe there is one or more callers, and then you simply move all in or put them all in. Example:
CO open to 2,3BB with a 20BB stack
BTN call with a 38BB stack
SB fold
Hero is BB with a 24BB stack and look down at KJs
In this situation Hero could just call and see a flop, and there is nothing really wrong with that. But its often a higher EV play to jam all in. A lot of the time CO wont have a hand, that is strong enough to call, and Hero also block some of the strong hands like AK, AJ, KK and JJ. And as for BTN he almost never have anything really good, because then he would usually have put in the reraise himself.
There is already around 7BB in the pot, and picking up those chips without having to connect with the board is a great outcome for Hero. Sometimes Hero will obviously get action, but even then he have
equity. Its only really bad for Hero, if he get called by JJ-AA, AK, AJ or KQ, and most of the time neither player will have those hands. Its also entirely possible, they will fold KQ and maybe even AJ, if they are conservative players.
Finding and taking on spots like this is maybe the largest difference between long term winners and people, who rarely make it further than "just in the money", because they are sitting on a short stack, once the bubble has burst. I hope, this helps
