“Some things are within our power, while others are not. Within our power are opinion, motivation, desire, aversion, and, in a word, whatever is of our own doing; not within our power are our body, our property, reputation, office, and, in a word, whatever is not of our own doing.” — Epictetus One of the core tenants of Stoicism is understanding the things we control and the things we cannot control. Clearly seeing things we do and don’t have control over is a skill that can impact every aspect of our lives. It can help lower our stress and help us make better and faster decisions. It can save us energy by focusing on the important things in our lives and letting go of the rest.
