I restore myself when I'm alone.

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

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

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.

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

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

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

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.

Absolutely lonely people have few personal interactions of any kind.
