Getting outdrawn

How do you deal with being drawn out on? I was watching the WSOP last nite and saw Men the Master flop top set. The amatuer flopped a flush draw. Men goes all-in and the other guy calls. The amatuer is about a 36% favorite but hit his flush to win. Men looked like he was gonna kill the guy. I believe in going all-in with the best of it but that early in the tournament you have to balance survival with aggression. Do you just put out medium bets until you see that the river is not dangerous?
