If revenge motivates you, go for it! But the main thing is to set your game in order.
Viswanathan AnandMy parents were very supportive of my chess. When I got home after a game of chess, having missed school or something, they always made me feel very welcome; I didn't feel guilty at all about pursuing chess with such fervour. They never, for instance, perceived sports as a rival to academics.
Viswanathan AnandJust before a game, I try to keep a clear mind so that I can focus better. I'm the kind of person who plays fast and relies a lot on intuition, so being at peace with myself is vital. Saying my daily prayers helps me achieve this heightened state of mind.
