Happiness is understanding that friendship is more precious than mere things, more precious than getting your own way, more precious than being in situations where true principles are not at stake.

Until you've tasted it [anything], you can't really know it.

If it (the good circumstances) changes will you be able to keep onto your happiness just as much? Because if not then your happiness is really built on sand.

Happiness is not a brilliant climax to years of grim struggle and anxiety. It is a long succession of little decisions simply to be happy in the moment.

In a sense, each of us is an island. In another sense, however, we are all one. For though islands appear separate, and may even be situated at great distances from one another, they are only extrusions of the same planet, Earth.

Be able to laugh at difficulties.

Happiness is like a plant: It must be watered daily with giving thoughts and actions.
