Morten Hansen, management professor at UC Berkeley, just released his new book, Great at Work: How Top Performers Do Less, Work Better, and Achieve More. This clip of his interview with Dan Pink is just one minute long, but he shares one of the vital secrets he writes about in the book—top performers “do less and obsess.” They pick 2-3 things that matter most and hyper-focus on them. Interestingly, this is also one of the central hypotheses of study skills author Cal Newport’s book How to Be a High School Superstar: A Revolutionary Plan to Get into College by Standing Out (Without Burning Out).

Most high school students don’t have the luxury of picking just one thing to obsess about. But there’s a good chance you could do less. If you’ve got activities that aren’t paying you back with fun or learning, if you’re sprinting from commitment to commitment with no real time to dive in and make a real impact, if your description of your life begins and ends with “busy,” it’s probably time to make some room in your life to obsess about the things that matter most to you. And the first step towards this healthy obsession is to do less.
