You cannot be lonely if you like the person you're alone with.

I finally faced the fact that it isn't a crime not having friends. Being alone means you have fewer problems.

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

Yes, I guess you could say I am a loner, but I feel more lonely in a crowed room with boring people than I feel on my own.

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

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

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.

Only the lonely know the way I feel tonight.

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

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