Only the lonely know the way I feel tonight.

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

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.

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

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

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

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

The capacity for not feeling lonely can carry a very real price, that of feeling nothing at all.

I love to be alone. I never found the companion that was so companionable as solitude.

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