Let me tell you this: If you meet a loner, no matter what they tell you, it’s not because they enjoy solitude. It’s because they have tried to blend into the world before, and people continue to disappoint them.

I used to think that the worst thing in life was to end up all alone.

It's not. The worst thing in life is ending up

with people who make you feel alone.

Robin Williams

I love to be alone. I never found the companion that was so compatible

 as solitude.

Henry David Thoreau

We're born alone, we live alone, we die alone. Only through our love 

and friendship can we create the illusion for the moment that we're

 not alone.

 Orson Welles

In order to be open to creativity, one must have the capacity for constructive

 use of solitude. One must overcome the fear of being alone.

Rollo May

The best part about being alone is that you really don't have to answer to anybody.

 You do what you want.

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

People in general disappoint me.

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

I had already found that it was not good to be alone, and so made

 companionship with what there was around me, 

sometimes with the universe and sometimes with my own

 insignificant self; but my books were always my friends,

 let fail all else.

Joshua Slocum

Without great solitude no serious work is possible.

Pablo Picasso

If you are afraid of being lonely, don't try to be right, or tell the truth."

You cannot be lonely if you like the person you're alone with.

Wayne Dyer.
