I'm a flighty person. I have a hard time focusing, and concentrating my efforts on my continual improvement. I have a job, I work 10 hour shifts, it makes it hard for me to focus completely when I play, and I am usually fairly tired.
I give in easily and make bad calls, because when I'm nearing exhaustion my fold button simply doesn't work. It would be ok to play like this occasionally if I had a proper bankrool, but because I'm a common working guy every tourney I play is more and more important and nearing the bubble, struggling to be sure I cash keeps me from optimal play...
I need to win the lottery, it's simple as that...
