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.

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.

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

All of our unhappiness comes from our inability to be alone.

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

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.
