A quitter never wins, and a winner never quits.
These short, inspiring words by Napoleon Hill can be comforting when we are at the edge of giving up. In situations where we worked hard and expect desirable results, and things don't go as planned, we tend to get discouraged and walk away. A quitter never wins, because success might be steps away. Moreover, the only way to achieve success is to keep trying because a winner never quits. They are willing to tackle any obstacle and challenge that comes their way. We are not born with skills or talent, it is learned from persistent habits and failure.
