Holiday is a marketing mogul turned Stoic guru whom the New York Times credits for the modern movement of ancient Stoicism as self-help. In this guide, we’ll provide specific strategies to help you exert Stoic discipline over both your internal world and the external world. We’ll also compare and contrast Holiday’s "life hack" Stoicism with the original philosophical texts that inspired it, as well as connect it to relevant contemporary self-help such as Grit by Angela Duckworth and Thinking in Bets by Annie Duke.
