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

Some cause happiness wherever they go others whenever they go.

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

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

Love is the master key that opens the gates of happiness.

Be more dedicated to making solid achievements than in running after swift but synthetic happiness.

An effort made for the happiness of others lifts above ourselves.

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

Action may not always bring happiness but there is no happiness without action.

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