You pay a price for getting stronger. You pay a price for getting faster. You pay a price for jumping higher. You pay a price for staying just the same. Because if you carry it any further, your competition is gaining ground.
Sweat is the lubricant of success.
Winners commit themselves to constant self-improvement. Proper preparation always moves the dream closer. There is a difference between interests and commitment. When you are interested in doing something, you only do it when it is convenient. When you are committed to something, you accept no excuses, only results.
