I spend quite a few minutes each day reminding my kid how important Mental Fitness is in order to suceed in any sport, especially tennis. I see a lot of Brittish tennis players losing it on court, verbal,racquet abuse, talking to themselves negatively and generally going to the "DARK SIDE" I advise my kid not to go to the darkside/get in a hole thats hard to get back out of while on court, when things get tough I also advise taking a toilet break between sets to refocus away from the scene of the "crime" (bad call,bounce,luck,etc) I File Mental Fitness in the INTELLIGENCE folder. My other folders contain SKILL, HEART (Desire & Physical) I classify these folders in the following order of importance. 1= Skill 2=Intelligence 3=Heart what folders do you have and what is their order of importance and why. regards, tricky.
