The game of business used to be like football: size mattered. Then it changed to basketball: speed and agility. Today, business is more like chess. Customer priorities change continually, and the signals given by these changes are vital clues to the next cycle of growth.
I always believe in going hard at everything, whether it is Latin or mathematics, boxing or football, but at the same time I want to keep the sense of proportion. It is never worth while to absolutely exhaust one's self or to take big chances unless for an adequate object. I want you to keep in training the faculties which would make you, if the need arose, able to put your last ounce of pluck and strength into a contest. But I do not want you to squander these qualities.
