It's important, according to me, to train in small doses so as to not lose the joy of playing chess. I personally think too many coaching and training classes may take away a child's interest in the game itself. The essential thing to do is practise often and, in case of a doubt, to consult a trainer.

Professional players work almost every day, for hours on end, and the emphasis is on the word 'work.' It can be with a partner or it can be alone, but professional chess is always a pursuit of something new and surprising.

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.

I would never suggest to anyone that they drop school for chess. First of all even if you can make it in chess, your social skills need to be developed there.

Grandmasters decline with age. That's a given. There is nothing special about the age of 40, but age eventually takes its toll. That much is clear. Beyond that it's about how long you can put off the effects and compensate for them. Mistakes will crop in but you try to compensate for them with experience and hard work.
