"If your determination is fixed, I do not counsel you to despair. Few things are impossible to diligence and skill. Great works are performed not by strength, but perseverance."
"I never could have done what I have done without the habits of punctuality, order, and diligence, without the determination to concentrate myself on one subject at a time..."

"Studies indicate that the one quality all successful people have is persistence. They're willing to spend more time accomplishing a task and to perservere in the face of many difficult odds. There's a very positive relationship between people's ability to accomplish any task and the time they're willing to spend on it."
"Most people give up just when they're about to achieve success. They quit on the one yard line. They give up at the last minute of the game one foot from a winning touchdown."
