Early on, I knew tilt was the most important thing and I tried like hell to undo it.  Sometimes I would practice losing in my car. … Then I would rehearse getting over it. … At the poker table, I practice losing for real.  When I lose a hand, I try to see it as practice for the next time I lose a hand.  If I go an hour without winning a pot, I’m just working out, getting in shape, for the next time I have a winless hour.  When I lose ten sessions in a row, I look at it as practice for the next time I lose ten sessions in a row.
