Writing is a socially acceptable form of schizophrenia.
E. L. Doctorow

I have spent this morning listening to the soft gurgling of a semicolon

I have bounced a couple of periods off the wall

A laundered sock is hanging on a comma

a field of exclamation marks stretches beyond the window

and sometimes the wind bends them into question marks

but no words come

No poet or novelist wishes he were the only one who ever lived, but most of them wish they were the only one alive, and quite a number fondly believe their wish has been granted.

W. H. Auden

If I don't write to empty my mind, I go mad. As to that regular, uninterrupted love of writing . . . I do not understand it. I feel it as a torture, which I must get rid of, but never as a pleasure. On the contrary, I think composition a great pain.

Lord Byron
