I get too impatient near at the middle point of a MTT and bust out on a stupid play most times.
I am a better shorthanded player so I play 2 or 3 STT at the same time.
Wait for the donkeys to knock eachother out and before you know it the 10 man STT is now a short handed game and I usually do fairly well.
Remember Google "Wheatley Poker" or "WHPT Poker" for info on the freerolls
