We all know the "chip and a chair" saying, but I often find it tough not to get discouraged when my stack gets crippled early in a tourney.
Last night, I was in an MTT (186 players) and had my stack knocked down to about 200 chips in the first round after a bad beat (honestly - miracle river).
Since the blinds were still low (10/20), I decided to be patient, pick my spots, and see what I could do to get back into the tourney. I was in last place out of 150, and still in last place with only 60 players left, but by being patient had managed to "tread water" for over an hour, while the field dwindled. After a while, I finally managed to put together a string of winning hands.
In the end, I made the money and finished 14th. I didn't win, but I watched player after player (who'd had way more chips than I did) get eliminated as I survived. Of course, this isn't the ideal way to play a tourney, but, as an exercise in patience, it was a good experience.
