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

All men's miseries derive from not being able to sit in a quiet room alone.

The capacity for not feeling lonely can carry a very real price, that of feeling nothing at all.

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

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

I finally faced the fact that it isn't a crime not having friends. Being alone means you have fewer problems.
