If you haven't ever finished writing a book, this is what you can expect if you ever do.
Step 1: Stare at the blinking cursor in disbelief. The mind floods with all sorts of chemicals that make you feel awesome and anxious at the same time.
Step 2: Like anything you create, you'll ponder whether or not it will teach others, make friends or just generally cause trouble.
Step 3: You'll want to print the darn thing out as quickly as you can, so you can hold it. The printer will (of course) be out of toner, so you'll have to go to the closest office barn and pay way too much for black gooey stuff for a machine to shoot out onto your paper.
Step 4: The darned thing will get printed out (finally) and you'll realize that you should have gone through it more first, added page numbers and other details that would help in the editing.
Step 5: You'll go and write something ridiculous on your blog or pat yourself on the back via Facebook, Google+, Twitter, etcetera.
Step 6: Suddenly, that sinking feeling will wash over you as you realize it's a first draft. Thousands of words you'll have to go through, over and over again, to make it right.
Step 7: The weight of a few thousand words rests a little lighter on whatever metaphysical force keeps you going. A little of what you were put on the Earth to do... is done.
Step 8: Smile.
