They often travel alone, playing alone, winning alone. No one there to enjoy his victory, or comfort his loss. When you enter a tournament, you begin an exciting process. Send in your entry fee. Post the tournament somewhere where you will see it often, then go into training.
Every session is in preparation for that event.
This gives your practice session more meaning. On the day of the tournament, treat yourself to a fine breakfast at a nice restaurant. This is a day you should enjoy. Win or lose, you need to treat yourself as the special person you are. During the matches, relax and turn in the performance that was meant for you that day.
