Going Hard

"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 worthwhile 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." Theodore Roosevelt
