It seems that ill spend hours reading and comprehending theories from various poker books, but as soon as i get in front of a computer it all goes to waste. My problem is that the 30 seconds or so i have to make a decision is often not enough time to think things through. I find myself panicking when i hear that beep and my mind just goes blank, im also making a lot of bad decisions when i multi-table because of this reason.
