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.

There are places and moments in which one is so completely alone that one sees the world entire.

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.

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

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

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

Every man is born as many men and dies as a single one.

Alone we can do so little together we can do so much.
