Imagine, if you will, you are about to play in a singles tournament and the tournament referee calls your name and introduces you to your opponent who is .... YOU. Same player, same ability. Now imagine one of the players looks at the other and thinks "Look at that schmuck. I'm gonna whip his ass. And when I've beaten his donkey I'm gonna beat him too". "He'll never be able to return my first serve and I'll crucify him with my forehand. I'll murder that pathetic second serve and make mincemeat of his ridiculously poor backhand". Now imagine the other player thinking "OMG my poor donkey. And he's gonna thrash me too. I'll never be able to return that first serve and he'll crucify me with his forehand. He'll murder my pathetic second serve and make mincemeat of my ridiculously poor backhand". Who do you reckon would win? Answers on a postcard (remember them?). The positive player would not only win but win comfortably. So be positive. Don't be your own opponent.
