Sleep more at night. If it’s allowed at work or home, take a nap in the afternoon. You’ll be amazed at how much better you’ll feel.

In this practical piece of advice, Stein frames sleep as a straightforward, underused lever for improving daily well-being. The quote suggests that many people treat fatigue as inevitable or as a badge of productivity, when in fact more rest—both overnight and via a short afternoon nap—can quickly improve mood, clarity, and resilience. By adding the conditional “if it’s allowed,” he acknowledges workplace and household norms that often discourage napping, implying that cultural permission matters as much as personal intention. The emphasis is not on discipline or optimization but on a simple bodily need: restore energy first, and performance and comfort follow.
