Unless we love and are loved, each of us is alone, each of us is deeply lonely.

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

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

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.

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

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

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