Effort only fully releases its reward after a person refuses to quit.

Before success comes in any man's life, he's sure to meet with much temporary defeat and, perhaps some failures. When defeat overtakes a man, the easiest and the most logical thing to do is to quit. That's exactly what the majority of men do. Napoleon Hill.

Quote on Perseverance

If one advances confidently in the direction of one's dreams, and endeavors to live the life which one has imagined, one will meet with a success unexpected in common hours.

-- Henry David Thoreau
