Your Inner Clock
The Art of Living in Rhythm For Night Owls, Early Birds, and Everyone BetweenBy Dr. Josh HarariLength1h 38m
About this audiobook
What if your daily struggles have less to do with discipline than with your biology? *Your Inner Clock: The Art of Living in Rhythm* explores the science of chronotypes—the biological rhythms that influence when you sleep, think, create, and perform at your best. Going beyond the familiar "early bird" and "night owl," the book introduces the **Light Hawk**, a flexible chronotype for those who fall between the two extremes. Blending circadian science with practical guidance, it explains how your internal clock shapes energy, mood, health, and productivity, why chronotypes evolve throughout life, and how to work *with* your natural rhythm instead of against it. Featuring the **Rhythm Spectrum Quiz**, this is a practical guide to understanding your body and designing a life that fits the way you're naturally wired.
