"Shitty first draft" is a technical term that I did not make up, but writers use this phrase all the time. It applies to writing and everything else: words, recipes, life, web design. And, its message is a simple one: You must start somewhere. With something.
I'm paraphrasing an author friend now. "I can improve bad copy, but there's nothing I can do with air."
I offer my author photos as an example. I explained my camera phobia to the fine folks at Port City Photography, and after about 250 frames, they captured the image above. It looks nice, right? Very author-ish and something to be proud of.
But consider if they had stopped at frame 247.
Challenge: Put your bum in the chair for one hour today and just write something.
