“What’s tranquility anyway? Seneca talks about the power of euthymia in his classic letters. He tells us that euthymia, which gets translated as tranquility, is all about knowing your path and walking that path. It’s the feeling we get when we truly and utterly trust ourselves. You’re confident that what you’re doing is right, and you don’t need to listen left and right for what others have to say. You don’t need to second guess and compare yourself to others all the time. You trust in what you’re doing because you’re trying your best, and you’re living accordingly to your values and know it’s all you can do.”
