Remember that the machine is there to help you, because at the end of the day, you're not playing freestyle chess, advanced chess, human-plus-machine. If you are playing against other humans, it's about winning the game. The machine will not be assisting you, unless you are cheating of course. And since the machine is not there, you have to make sure that everything you learn from the computer will not badly affect the way you play the real game.

One lesson is to not to play desperately if your position is worse but still reasonable. Lashing out wildly in an inferior position usually only hastens defeat. Meanwhile, solid, stubborn defense can demoralize the attacker, make him lose confidence. When that happens, the tables can turn. Keep fighting, stay steady, keep morale high - and public protests are good for all of these things.

Where do poor young people turn? ISIS has a mission for you to change the world! It's a horrific vision, but it's a vision. Perhaps for white supremacists, you can add the additional storyline that they believe that they are having something taken from them by outsiders, by immigrants. Not only are they losing out and bored, but they think they are victims and that they know who is responsible.

Chess is an art and not a spectator sport.

It is quite difficult to establish a clear-cut cause-and-effect relationship, as the causes are manifold and closely connected. It is simply not correct to link the level of democracy to prosperity. It is absolutely clear that the economic wealth of Saudi Arabia exceeds the performance of the Czech Republic. But apparently democracy is quite stable in the Czech Republic, which cannot be said about Saudi Arabia. As we delve into the past, we must not forget about the existing model of society.

Learning from our mistakes is critical for improving, but even I don't have patience for ranking my regrets. Regret is a negative emotion that inhibits the optimism required to take on new challenges. You risk living in an alternative universe, where if only you had done this or that differently, things would be better. That's a poor substitute for making your actual life better, or improving the lives of others. Regret briefly, analyze and understand, and then move on, improving the only life you have.

If you're already in a fight, you want the first blow to be the last and you had better be the one to throw it.
