Aspire greatly; anything less than a commitment to excellence becomes an acceptance of mediocrity.
Leaders set high standards. Refuse to tolerate mediocrity or poor performance.
Self-discipline is the key to personal greatness. It is the magic quality that opens all doors for you, and makes everything else possible.

But without self-discipline, a person with every blessing of background, education and opportunity will seldom rise above mediocrity.
