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.

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

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

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

When so many are lonely as seem to be lonely, it would be inexcusably selfish to be lonely alone.

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

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

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

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

Love is our true destiny. We do not find the meaning of life by ourselves alone - we find it with another.
