In this episode, Lucas and Luna dive into the concept of an energy audit — tracking not just how you spend your time, but how each task affects your energy. Lucas shares a personal experiment where he logged his energy levels every hour for a week, revealing surprising patterns: certain low-effort tasks drained him more than high-focus work. Luna brings in research from the University of California showing that knowledge workers have, on average, only three to four truly productive hours per day. Together, they discuss how to use an energy audit to redesign your calendar around your natural rhythms, set boundaries that protect your peak hours, and stop feeling guilty about scheduling deep work when your energy is highest. Lucas also offers a simple template listeners can use to run their own energy audit starting tomorrow. This episode is practical, data-driven, and perfect for anyone who feels tired all the time but isn't sure why.
