“SELF-DISCIPLINE, more than any other personal quality I can think of, is the one thing that separates successful people from the unsuccessful. Think of all it encompasses: honoring commitments, promises and deadlines, keeping your life on schedule, being willing to go the extra mile... Self-discipline is essential to success. The alternative is a life ruled by emotions, and none of us can afford that if we're going to fulfill our purpose and realize our potential.”
