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

Friendship improves happiness and abates misery, by the doubling of our joy and the dividing of our grief.

The word 'happiness' would lose its meaning if it were not balanced by sadness.

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

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

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

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

It is not how much we have, but how much we enjoy, that makes happiness.

Happiness is beneficial for the body, but it is grief that develops the powers of the mind.

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