You know it's love when all you want is that person to be happy, even if you're not part of their happiness.

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

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

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

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

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

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

Always leave something to wish for otherwise you will be miserable from your very happiness.

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

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