Morality is not the doctrine of how we may make ourselves happy, but how we may make ourselves worthy of happiness.

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

All who joy would win must share it. Happiness was born a Twin.

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

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

Happiness is not a reward - it is a consequence. Suffering is not a punishment - it is a result.

Love is when the other person's happiness is more important than your own.

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

Three grand essentials to happiness in this life are something to do, something to love, and something to hope for.

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