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

If it's true that our species is alone in the universe, then I'd have to say the universe aimed rather low and settled for very little.

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

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

It is strange to be known so universally and yet to be so lonely.

The time you feel lonely is the time you most need to be by yourself.

Unless we love and are loved, each of us is alone, each of us is deeply lonely.
