Satisfaction of one's curiosity is one of the greatest sources of happiness in life.

What we call the secret of happiness is no more a secret than our willingness to choose life.

Never make friends with people who are above or below you in status. Such friendships will never give you any happiness.

Most folks are as happy as they make up their minds to be.

Do not speak of your happiness to one less fortunate than yourself.

It is not how much we have, but how much we enjoy, that makes happiness.

Happiness doesn't depend on any external conditions, it is governed by our mental attitude.

There is only one happiness in this life, to love and be loved.

Life does not agree with philosophy: There is no happiness that is not idleness, and only what is useless is pleasurable.

The secret to happiness is freedom... And the secret to freedom is courage.
