Take a Deep Breath
I think you are exactly right. Too many times when I take a beat like that, I get in a big rush to get back all the chips I just lost and usually bust out of the tournament completely.
We should look at the situation like this...Everyone's goal should be to finish first in every tournament we play in. However, most of the time that isn't going to happen because the odds
are stacked against us. But we should always strive to overcome those odds to win. When we take a big hit from a bad beat, the odds become stacked against us even more...but we still have a chance, it is still possible to win if we still have chips. If we go on tilt and throw our chips in right away out of frustration, we will probably lose all of our chips...and when all of our chips are gone we have no chance to win the tournament (we have given in to the odds).
No matter how big your chip stack is, always strive for a win. Learn to play all stages of a tournament with all sizes of chip stacks. It takes patience and determination to win. Sometimes the cards seem to work against us but be assured they will soon start falling your way...Never give up.
