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

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.

Living alone makes it harder to find someone to blame.

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.

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.
