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

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

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

Success is not the key to happiness. Happiness is the key to success. If you love what you are doing, you will be successful.

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

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

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.

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

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