Satisfaction of one's curiosity is one of the greatest sources of happiness in life.

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

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.

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

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

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

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

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

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