Imagine a takeout pizza restaurant run entirely by one woman. She opens the store in the morning, receives shipments, does food prep, takes orders, makes pizzas, delivers them, closes at night, files paperwork, and cleans up. By the end of the day she only gets a few dozen pizzas to customers. And as she's going to sleep, she tosses and turns, worrying that she didn't get enough done.

Now imagine her sole task for the day was to prep ingredients. How do you think she'd sleep?
