Do you have a mental preparation routine you use prior to each competition? The pregame warm up is much more than a physical warm up. You have to use this time to be mentally ready to compete. Most top athletes use pregame mental preparation routines to feel ready to perform their best and consistently perform up to their physical talent! 
Mental preparation is one of the most important parts of an individual’s sports performance. Some players have all the skills in the world, but if they are not mentally prepared they will not be able to implement their skills through the duration of "game time". One of the best ways to be mentally prepared is to practice visualization.
