The one happiness is to shut one's door upon a little room, with a table before one, and to create to create life in that isolation from life.

The groundwork of all happiness is health.

It's good to follow the path of personal happiness to some extent. People tend to get upset however when you drive a steamroller down it.

Happiness consists in activity. It is running steam, not a stagnant pool.

The pursuit of happiness is in our Constitution. We're all entitled to have the best we can.
