“If you seek tranquility, do less . . . do what’s essential.” This will bring a double satisfaction, says Marcus Aurelius, “to do less, better.” Ask yourself, “What are the most important things in my life?” Once you know what those things are, you need to prioritize them. And eliminate what didn’t make the list. This will gain you time and tranquility. Like everybody else, you have 24 hours in a day. And you choose how to spend those hours.
