Absolutely lonely people have few personal interactions of any kind.

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.

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.

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

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

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

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