A few quotes about writing for today:

Meaningful, and particularly appropriate for NaNoWriMo:

“There is nothing to writing. All you do is sit down at a typewriter and bleed.” 
― Ernest Hemingway

"There is no greater agony than bearing an untold story inside you."
― Maya Angelou

Good to remember:

“The road to hell is paved with adverbs.”
― Stephen King

And all too true:

“I love deadlines. I love the whooshing noise they make as they go by.”
― Douglas Adams

But be careful going through there. I've found GoodReads quotes not always reliable. Sometimes misquoted, sometimes missattributed, sometimes just a bit mistaken.
