Relax and do relaxing things. Go to sleep early. Sleep helps you to process and incorporate everything that occurred during the day.
Discuss tournament with teammates but only in a positive manner. no matter the outcome of the tournament. Discuss what needs to be done for improvement. Return to routine training using all you have learned to adapt the training toward improving your performance.
Tournaments are a learning experience, an opportunity to put your skills to the test, and an opportunity to meet old friends and make new friends. Do not get discouraged if you lose, do not get cocky if you win. Tournaments should be fun; if they are not fun, then you are doing something wrong.
