The time you feel lonely is the time you most need to be by yourself.

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.

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

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

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.

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

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

The only real progress lies in learning to be wrong all alone.

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