Willpower is a mental resource that determines how easy it is to start working, resist junk food, or go to the gym. It's like a muscle that can be flexed and relaxed as needed, strengthened with training, and lost if not used enough. Strengthening willpower requires a combination of good health habits, including diet, exercise, sleep, hydration, and meditation, which help build resilience and improve focus. Additionally, creating an environment that reduces the need for willpower, such as minimizing distractions and temptations, can maximize its use. By breaking down tasks into manageable chunks, making them a habit, avoiding bad news, and pre-committing to specific actions, individuals can conserve their willpower and make progress towards their goals.
