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

Absolutely lonely people have few personal interactions of any kind.

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

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

Look at the sky. We are not alone. The whole universe is friendly to us and conspires only to give the best to those who dream and work.

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

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

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