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

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

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

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

Happiness lies in the joy of achievement and the thrill of creative effort.

Success is getting what you want. Happiness is wanting what you get.

Some cause happiness wherever they go others whenever they go.

Be happy for this moment. This moment is your life.

The happiness of this life depends less on what befalls you than the way in which you take it.

It is not in the pursuit of happiness that we find fulfillment, it is in the happiness of pursuit.
