The emotion I’m most comfortable with is guilt (Thanks mom!). In the early days of my business, when I would wake up with a start at 3 am with a line of drool connecting my lower lip to my keyboard, I would beat myself up. How could I nap after a mere seventeen hours of work when there were kids in Cupertino forgoing sleep for five days at a stretch? It’s a good thing I came across this book before ending up in a hospital ward with total organ failure. Pang makes a compelling case that most of the stories about business builders who work 365 days straight on 3 hours of sleep each night are image-building myths. His book shows why quality rest is the ideal fuel for creative and commercial productivity and provides a recipe for how to use it to up your chances of achieving your most audacious goals.
