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

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

Happiness is not something ready made. It comes from your own actions.

What we call the secret of happiness is no more a secret than our willingness to choose life.

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.

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

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

Do not speak of your happiness to one less fortunate than yourself.

Most folks are as happy as they make up their minds to be.
