Memento 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?

Leo TolstoyPatience is waiting. Not passively waiting. That is laziness. But to keep going when the going is hard and slow - that is patience. The two most powerful warriors are patience and time.
