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.

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 paint self-portraits because I am so often alone, because I am the person I know best.

If you are lonely when you're alone, you are in bad company.

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

Always give a word or sign of salute when meeting or passing a friend, or even a stranger, if in a lonely place.

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

I have so many different personalities in me and I still feel lonely.

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

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