Self-discipline is the key to personal greatness. It is the magic quality that opens all doors for you, and makes everything else possible. With self-discipline, the average person can rise as far and as fast as his talents and intelligence can take him. But without self-discipline, a person with every blessing of background, education and opportunity will seldom rise above mediocrity.
