In "The Daily Stoic," Ryan Holiday explores the idea that rigid adherence to consistency can limit one's thinking and understanding. He references Ralph Waldo Emerson's assertion that this type of foolish consistency is often embraced by those with limited perspectives—such as certain politicians, philosophers, and religious leaders. By clinging too tightly to past beliefs or methods, individuals may miss out on growth and the opportunity to evolve their thoughts.

Holiday encourages readers to be open-minded and adaptable instead of being constrained by the fear of changing their views. Embracing flexibility allows for a richer, more nuanced understanding of life and its complexities. The wisdom of Stoicism supports this notion, as it teaches the importance of being present and responsive to the current moment rather than adhering to an outdated or dogmatic way of thinking.
