I paint self-portraits because I am so often alone, because I am the person I know best.

Always give a word or sign of salute when meeting or passing a friend, or even a stranger, if in a lonely place.

What a lovely surprise to finally discover how unlonely being alone can be.

Every man must do two things alone he must do his own believing and his own dying.

I finally faced the fact that it isn't a crime not having friends. Being alone means you have fewer problems.

As I get older I'm more and more comfortable being alone.

The only real progress lies in learning to be wrong all alone.

You cannot be lonely if you like the person you're alone with.

Even in the presence of others he was completely alone.

I don't want to be alone, I want to be left alone.
