Preparation is the key to everything. I use the whole afternoon just to prepare.
In the morning I play at least 200 hands with Advanced Poker Training -software. Then I go to the gym. But not too hard work out, just reduce my stress. Then I come back to home and I eat something and watching some series Simpsons, South Park etc. funny. Then I take a nap for 20-30 min. And of course, I drink some coffee to get energized. Then I play chess for 20 minutes. Then it is action time. I open the poker software, PokerTracker and screen recording software. I screen record every session. Also, I drink green tea and I eat a little bit of dark chocolate while I am playing. This routine really works. And after a poker session, I post my biggest problem hand to CardsChat hand analysis forum.
