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

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

Love is our true destiny. We do not find the meaning of life by ourselves alone - we find it with another.

If it's true that our species is alone in the universe, then I'd have to say the universe aimed rather low and settled for very little.

As I get older I'm more and more comfortable being alone.

Even in the presence of others he was completely alone.

If you are lonely when you're alone, you are in bad company.

I don't want to be alone, I want to be left alone.

Yes, I guess you could say I am a loner, but I feel more lonely in a crowed room with boring people than I feel on my own.

I restore myself when I'm alone.
