This document outlines daily practices for developing mental toughness and reaching peak performance. It discusses four main practices: (1) being the dumbest person in the room to challenge your ego and learn from others; (2) taking cold showers to increase discomfort tolerance; (3) practicing failure through risk-taking and using "no" therapy; and (4) intermittent fasting to generate focus through sacrifice. The document provides reasons and suggestions for how to implement each practice, and closes by having participants partner up to hold each other accountable to the practices discussed.
