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

I restore myself when I'm alone.

A man content to go to heaven alone will never go to heaven.

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.

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

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

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

Living alone makes it harder to find someone to blame.
