Amazing, but honestly, not surprising:
Whether you’re a student or well along in your career, if your goal is to build a remarkable life, then busyness and exhaustion should be your enemy. If you’re chronically stressed and up late working, you’re doing something wrong. You’re the average players from the Universität der Künste — not the elite. You’ve built a life around hard to do work, not hard work.
The solution suggested by this research, as well as my own, is as simple as it is startling: Do less. But do what you do with complete and hard focus. Then when you’re done be done, and go enjoy the rest of the day.
