Sleep is not an escape for being idle. Sleep is restorative. Sleep feels good when we’re sleeping off a productive day. If hard work doesn’t precede sleep, there’s little need for rest. Idleness requires a jolt – not a nap. Our bodies thank us for a good night’s sleep after a hard worked day, and jolt our minds into knowing that good feeling, creating habits of desire for doing good work. Conversely, our minds will tell our bodies to stay mindlessly idle, burning fuel while going nowhere, when it senses we habitually use our time poorly.
