It is your responsibility to make sure that positive emotions constitute the dominating influence of your mind.

Effort only fully releases its reward after a person refuses to quit.

If you must let someone down, be sure it isn’t the friend who helped you up when you were down.

Achieve self-mastery over your thoughts, and constantly direct them toward your goals and objectives. Learn to focus your attention on the goals that you want to achieve and on finding ways to achieve those goals.

Your real courage shows best in the hour of adversity.

No one could become an efficient leader or take the initiative in any great undertaking without belief in himself.

Self-confidence results, first, from exact knowledge; second, the ability to impart that knowledge.
