You had your hours planned out and still didn’t get everything done. Dave and Luke tackle one of the biggest misconceptions about productivity: that a better calendar or a tighter system is the answer to getting more from your time.

Their case is simple. A day is fixed at 24 hours, but energy is the variable that determines what you can do with it. They break down the four types of energy we all carry, the difference between real and fake recovery, and a framework for building your day around your actual energy instead of your calendar.
