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

Living alone makes it harder to find someone to blame.

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

I restore myself when I'm alone.

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.

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.

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

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

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