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

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

The best part about being alone is that you really don't have to answer to anybody. You do what you want.

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

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

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

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

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