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.

We are all sentenced to solitary confinement inside our own skins, for life.

All men's miseries derive from not being able to sit in a quiet room alone.

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

The capacity for not feeling lonely can carry a very real price, that of feeling nothing at all.

I never said, 'I want to be alone.' I only said, 'I want to be left alone.' There is all the difference.

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

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

A man content to go to heaven alone will never go to heaven.
