Cut those potatoes into 12 slices, but don't cut all the way through like a critic's opinion of your new book.
Put those potatoes on a plate and cheat. Think of it as giving yourself a little boost. Drink some wine. Put the potato plate in the microwave and nuke them for five minutes.
Think that your next book should feature potatoes, microwaves, and wine.
Celebrate yourself and your idea.
Get aluminum foil and tear it into four big pieces of awesome. Think of each piece as a happy section of your book. Vow to write your next book in sections as you put a potato on the center of each piece of aluminum foil.
Brush the garlic and butter in between the potato slices. DO NOT THINK OF THESE HOLES AS PLOT HOLES! Do not realize suddenly that there are plot holes in your book that just came out today. There aren't. You are just being neurotic, writer!
Step away from your cell phone. Do not call anyone. Big breaths. Focus on potatoes.
Encase those potatoes in the foil so they are all tightly closed in. Look at that! It's a nicely tight plot. No holes! See? Aren't you glad you didn't call or email or panic or anything?
Cook 30 minutes.
Take the potatoes off the grill. Be careful. Open up the packages and put pieces of cheese in between the slices. Your potato will not adhere to itself like a beautiful book narrative.
Wrap them back up.
Put them back on the grill for another five minutes or so.
Celebrate. You've created something great! Season that greatness if you feel like it.
