Suck outs seem so much worse than they actually are when it knocks you out - but keep in mind the players making these poor EV moves are also the ones who make your monster stack the games that you are doing well in. Keep in mind that even 4 outs on the flop has ~20% chance of beating you, so 1 out of 5 times you will lose - and you will be in that situation way more than 5 times in one tournament.
