Part 3/8:
At the core of stoic philosophy, as highlighted in the book, is the critical distinction between what is within our control and what is not. According to Brian, this fundamental principle serves as a vital tool for personal growth. He reminds viewers of the Serenity Prayer: "God grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference." This encapsulation of stoicism urges individuals to focus on their actions and thoughts, underscoring the importance of maintaining virtue in every situation.
