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

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

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

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 misfortunes spring from their hatred of being alone.

Even in the presence of others he was completely alone.

There are places and moments in which one is so completely alone that one sees the world entire.

I have so many different personalities in me and I still feel lonely.

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

I restore myself when I'm alone.
