"Continuous effort -- not strength or intelligence -- is the key to unlocking our potential."
"If you train hard, you'll not only be hard, you'll be hard to beat."
"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."
-Theodore Roosevelt, Theodore Roosevelt’s Letters to His Children (1919)
"The most challenging aspect of the decathlon is not the events themselves, but how you train to become the best 100-meter runner you are on the same day that you're the best 1,500-meter runner."
"There are no short cuts to any place worth going."
"The more I train, the more I realize I have more speed in me."
