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

Happiness depends more on how life strikes you than on what happens.

Choose your life's mate carefully. From this one decision will come 90 percent of all your happiness or misery.

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

Happiness is not an ideal of reason, but of imagination.

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

I do believe that if you haven't learnt about sadness, you cannot appreciate happiness.

To find out what one is fitted to do, and to secure an opportunity to do it, is the key to happiness.

Happiness is not something ready made. It comes from your own actions.

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