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

All of our unhappiness comes from our inability to be alone.

It's often just enough to be with someone. I don't need to touch them. Not even talk. A feeling passes between you both. You're not alone.

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

All men's misfortunes spring from their hatred of being alone.

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

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

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

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.
