Here's some quotes I found, followed by my take.
"Anyone could write a novel, given six weeks, pen, paper, and no telephone or wife."
Evelyn WaughNow substitute wife with husband and children, pen and paper with laptop, no telephone with the internet and you might have something there.
"What creates a writer is huge, psychological dysfunction."
I used to firmly believe that I could never be a writer, because nothing interesting or psychologically bad ever happened to me."I was working on the proof of one of my poems all the morning and took out a comma. In the afternoon, I put it back in."
Oscar WildeEven the greats revise, even it it's just one comma at a time.
"Let other pens dwell on guilt and misery. I quit such odious subjects as soon as I can.'
AMEN - but that's just me.
"Better to write twaddle, anything, than nothing at all."
Except replace the word twaddle with the word crap, and that's one of my favorite sayings. One I say over and over in my head as I'm writing a first draft, although I'm not entirely sure what twaddle means.
Okay maybe it wasn't as short as I thought it was going to be.
