Writers who have delved into human nature, ancient masters of strategy, historians of human stupidity and folly, kings and queens who have learned the hard way how to handle the burden of power, there knowledge is gathering dust, waiting for you to come and stand on their shoulders. Their wit can be your wit, their skill can be your skill, and they will never come around to tell people how unoriginal you really are. You can slog through life, make endless mistakes, wasting time and energy trying to do things from your own experience. Or you can use the armies of the past. As Bismarck once said, 'Fools say that they learn by experience. I prefer to profit by others' experience.'
