" Mentally practice two or three times each week for about 10 to 15 minutes per rehearsal. Select a specific sports skill to further develop, or work your way though different scenarios, incorporating various game-ending situations. Examples include meeting your marathon goal time, striking out the side in the bottom of the ninth, or making the game-winning shot as the final buzzer is sounding. Mental practice sessions that are shorter in length are also beneficial. Good times include during any downtime in your schedule, the night before a competition, as an element of your pregame routine, and especially as part of a preshot routine. "
