It's true that in chess as in politics, fund-raising and glad-handing matter.

There is no one that can share your responsibility. It it is your responsibility you must carry it on and you must be responsible for your actions. At the end of the day we all are being challenged, sooner or later, by our destiny. And it's up to us to make all the difference in this life. If not you, who else?

I would say that when you go to the very, very top, it's an ability to come up with new ideas, with something new, to make the difference.

For young players, their minds are not overloaded. I am 54 with four kids and I do many other things. Even if I stopped everything else, spent months working just on chess, for a long match against most of the top players, a classical match, six hours, say, I don't stand a chance. I have a better chance in shorter matches. Rapid is 25 minutes, or blitz events where you have five minutes to make a move, or bullet games, where it is one minute. For blitz, five-minutes chess, I would be top ten, top five. But longer games, no chance.
