I'm not in favour of a regulation-free world. I align myself with Teddy Roosevelt, who broke up the trusts. Regulation is necessary, but it should be in favour of the consumer, the citizen, and freedom.

Setbacks and losses are both inevitable and essential if you're going to improve and become a good, even great, competitor. The art is in avoiding catastrophic losses in the key battles.

A master looks at every move he would like to make, especially the impossible ones

Chess is an art and not a spectator sport.

Ultimately, what separates a winner from a loser at the grandmaster level is the willingness to do the unthinkable. A brilliant strategy is, certainly, a matter of intelligence, but intelligence without audaciousness is not enough. Given the opportunity, I must have the guts to explode the game, to upend my opponent's thinking and, in so doing, unnerve him. So it is in business: One does not succeed by sticking to convention. When your opponent can easily anticipate every move you make, your strategy deteriorates and becomes commoditized.
