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

There is only one happiness in this life, to love and be loved.

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

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

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

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

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

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

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

Remember happiness doesn't depend upon who you are or what you have it depends solely on what you think.
