This article discusses the core principle of Stoicism, which is to focus on what you can control and not worry about what you can't. It draws from the teachings of Epictetus and Marcus Aurelius, emphasizing the importance of dividing concerns into two categories: your actions and choices (the small bin you are responsible for) and everything else (the large bin that is the responsibility of the gods). The author explains that much of our suffering comes from trying to control the uncontrollable, and that true freedom and peace come from focusing on our own will and actions. The article also touches on the similarities between Stoicism and Buddhism, both of which emphasize letting go of the need to control everything. The author encourages readers to practice this principle daily, shrinking their sphere of concern to match their sphere of influence.

The core idea of this article, rooted in Stoicism, is to "focus your energy on what you can control and accept what you can't." While this sounds simple and practical, life is often more complex. For example, your job might bring pressure and unhappiness, even though it provides income. While you could control this situation, it would require significant effort. Ultimately, it comes down to identifying what matters most to you and then directing your energy accordingly.
