Have you ever made a mistake at the poker table and then spent hours (or even days in some cases) berating and criticizing yourself? Do you constantly replay or obsess over mistakes, near misses, or negative situations?
The mental process of replaying mistakes in high definition is called rumination and it has led many a poker player into the pits of despair. Once self-doubt creeps in, it is hard to get back into the groove of playing well. To deal with this effectively, you need to know how to handle setbacks during an event as well as after.
