I keep forcing, I keep learning new things in the game, and so far I have been taking challenges as they come.
For me, each game is a new challenge, which has to be dealt with rationally and systematically. At that time, every other thought fades into oblivion.
I attend to my fitness. I go the gym every day and try to maintain my physical fitness; without that, it is tough to take challenges on the chess board.
It is important that you don't let your opponent impose his style of play on you. A part of that begins mentally. At the chessboard if you start blinking every time he challenges you then in a certain sense you are withdrawing. That is very important to avoid.
