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

Happiness is when what you think, what you say, and what you do are in harmony.

Three grand essentials to happiness in this life are something to do, something to love, and something to hope for.

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

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

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

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

The true secret of happiness lies in taking a genuine interest in all the details of daily life.

Happiness depends more on how life strikes you than on what happens.

All happiness or unhappiness solely depends upon the quality of the object to which we are attached by love.
