Nervous energy is the ammunition we take into any mental battle. If you don't have enough of it, your concentration will fade. If you have a surplus, the results will explode.

If we look at statistical data, we see that Protestant countries in terms of economic development are more successful than those observing Catholicism.

With some reservation, it can be said that certain democratic elements are present in Georgia as well; but it is very clear that the government has to pronounce its explicit wish to resign before something is going to happen. On the western front, only Belarus is an exception.

If critics and competitors can't match your results, they will often denigrate the way you achieve them. Fast, intuitive types are called lazy. Dedicated burners of the midnight oil are called obsessed.

We must be optimistic about the future because it's a self-fulfilling prophecy. If we are creative and ambitious, intelligent machines will liberate us and be as profound a boon to our prosperity as electricity. If we are fearful, and fail to press ahead, we could be overwhelmed by automation and inequality.

Perfectly correct chess exists only in theory.
