About this listen

Why does discipline feel strong in the morning and disappear by night? In this episode, we unpack a more realistic view of willpower - not as a personality trait, but as a limited and renewable mental resource.


Using research on cognitive load, decision fatigue, and classic studies like the Israeli judge parole data and the cookie-versus-radish experiment, we explore why good intentions collapse under daily demands. We discuss how environment, routine, and micro-habits protect mental energy, why trying harder often backfires, and how real change comes from designing your life to reduce decisions rather than relying on motivation. This episode offers a grounded framework for building sustainable discipline without self-punishment.
