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

I don't want to be alone, I want to be left alone.

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

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

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.

Every man is born as many men and dies as a single one.

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

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