The more you learn what to do with yourself, and the more you do for others, the more you will learn to enjoy the abundant life.

Never mind what others do; do better than yourself, beat your own record from day to day, and you are a success.

That you may retain your self-respect, it is better to displease the people by doing what you know is right, than to temporarily please them by doing what you know is wrong.

No man will succeed unless he is ready to face and overcome difficulties and prepared to assume responsibilities.

You cannot build character and courage by destroying men's initiative and independence.

You can succeed if nobody else believes it, but you will never succeed if you don't believe in yourself.

Your success depends mainly upon what you think of yourself and whether you believe in yourself.

Your greatness is measured by your kindness.

Beware of ignorance when in motion; look out for inexperience when in action, and beware of the majority when mentally poisoned with misinformation, for collective ignorance does not become wisdom.

You cannot raise a man up by calling him down.

You cannot strengthen the weak by weakening the strong.

Perseverance is a positive, active characteristic. It is not idly, passively waiting and hoping for some good thing to happen.

One of my most productive days was throwing away 1,000 lines of code.

We see light, not dark. But it is in the dark that we feel goblins and ghosts.
