"For such a fight, you must train hard to just develop the self confidence to enter such a match . You must, by way of your self confidence, know that you can win . When Ving Tsun (Wing Chun) practitioners go to fight and are defeated then the mentality is not to think that the other person is better than himself . Instead he needs to ask himself what were his mistakes to invite the attack . This is the kind of positive thinking which any fighter must possess."
