A man on a thousand mile walk has to forget his goal and say to himself every morning, 'Today I'm going to cover twenty-five miles and then rest up and sleep.
Leo TolstoyIn order to understand, observe, deduce, man must first be conscious of himself as alive.
Leo TolstoyMemento mori - remember death! These are important words. If we kept in mind that we will soon inevitably die, our lives would be completely different. If a person knows that he will die in a half hour, he certainly will not bother doing trivial, stupid, or, especially, bad things during this half hour. Perhaps you have half a century before you die-what makes this any different from a half hour?
