Absolutely lonely people have few personal interactions of any kind.

It's often just enough to be with someone. I don't need to touch them. Not even talk. A feeling passes between you both. You're not alone.

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

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

The best part about being alone is that you really don't have to answer to anybody. You do what you want.

We are all sentenced to solitary confinement inside our own skins, for life.

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

It is strange to be known so universally and yet to be so lonely.

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

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