A vital part of the happiness formula is self-discipline. Whoever conquers himself knows deep happiness that fills the heart with joy.

Stand up to your obstacles and do something about them. You will find that they haven't half the strength you think they have.

By success, of course, I do not mean that you may become rich, famous, or powerful for that does not, of necessity, represent achievement. Indeed, not infrequently, such individuals represent pathetic failure as persons.

Believe in yourself! Have faith in your abilities! Without a humble but reasonable confidence in your own powers you cannot be successful or happy.

Only the person who risks is truly free. A man's conquest of himself dwarfs the conquest of Mt. Everest.

Don't bother. The glass is half-empty.

Change your thoughts and you change your world.
