Commitment

Commitment is what transforms a promise into reality. It is the words that speak boldly of your intentions, and the actions which speak louder than the words. It is making the time when there is none—coming through time after time after time, year after year after year. Commitment is the stuff character is made of; the power to change the face of things. It is the daily triumph of integrity over skepticism.
