I recently read Roy Baumeister’s book “Willpower: Rediscovering the Greatest Human Strength.” This book is a practical guide to understand your willpower and how to manage and preserve it. It is basically science applied to help people in very simple and useful ways. Read it.
This book led me to read other works by Roy Baumeister and I now recommend reading basically everything ever written by Roy Baumeister. He wrote the somewhat anti-feminist book “Is There Anything Good About Men?: How Cultures Flourish by Exploiting Men” and studied female sexuality in his extremely interesting works on erotic plasticity (Baumeister, R. F. (2000). Gender Differences in Erotic Plasticity: The Female Sex Drive as Socially Flexible and Responsive. Psychological Bulletin, 126(3), 347-374). All these subjects have relation to game, self-improvement and anti-feminism and are of interest to many young men and to the manosphere.
Roy Baumeister is a very unexpected to red-pill/manosphere ally in the academic world.
