Until this past year, I had no idea I was a practicing Stoic but I have been for much of my life, I just never knew there was a name for it.
"Stoicism holds that we can only rely on our responses to outside events, while the events themselves we cannot control."
NJ Lifehacks has done a brilliant job at breaking down the definition of Stoicism:
Eudaimonia: At the core of this new approach to Stoicism lies eudaimonia—the ultimate goal of life all ancient philosophies agreed on. The Greek origin of the word means being on good terms (eu) with your inner daimon, your highest self. It often gets translated as supreme happiness and is about thriving in our lives. It’s what we all want, to thrive and live a happy life. And how can we achieve this? By living with the three principles of the Stoic Happiness Triangle.
Live with Areté: This is about being your best version in the here and now. If we want to live that supremely happy life, we need to express our best self in every moment. It’s about aligning our chosen actions with our deep values.
Focus on What You Control: This is the most prominent principle in Stoicism. The Stoics realized that there are things we control, and things we don’t control. To get to the good life, we should focus on the things we control, and accept the rest as it happens. We can’t change what already is, but we can choose what to do with the given circumstances. Let’s focus on that.
Take Responsibility: Even if we don’t control everything that happens, we must take responsibility for our own lives. Because every event offers an area we control, namely how we judge the event and how we choose to respond. This is crucial in Stoicism, it’s not an external situation that makes us happy or miserable, but our interpretation of that situation. If we take responsibility and don’t let outside events determine our wellbeing, then we can express our best self and become supremely happy.
I am a fan of Ryan Holiday's books on stoicism including "Stillness is the Key" and "Obstacle is the Way" along with the Daily Stoic.
