Ah, when the work is done, you think, "it was worth it." The mess is soon forgotten as you gaze at the dazzling new kitchen. Appliances actually work. New cabinets provide the storage you've always desired. Yeah, I'd do it all over again.
Writing a book is a lot like a home improvement project. You plan, brainstorm, gather the required materials, and get to work. The vision of a book with your name on it propels you. Excitement ripples through your fingers and onto the keyboard.
Then come the minor disasters, followed by major revisions. You rip out a paragraph, sometimes even a chapter, and re-write it. My first draft wasn't pretty, folks, but I edited, revised, chopped out pieces here and there. It's looking better every day to me. (Hopefully, an editor will agree.)
So, don't let first, second, and even third-draft blues get you down. Keep learning, polishing, and you'll soon have a finished product. Maybe I'll actually hear an agent or editor say, "I like it. I want it. Write two more."
