Bob Pozen does a lot. He’s been a top executive at two mutual fund giants, Fidelity and MFS Investment Management. He’s also been an attorney, a government official, a law school professor, a business school professor, and a prolific author. And he has often been several of those things at once. Yet Pozen never comes across as overwhelmed, frazzled, or even all that busy. We know this because he’s a frequent contributor to HBR and hbr.org—with a reputation around our offices for writing faster than we can edit. Our experiences with him led us to wonder if he might have something interesting to say about personal productivity. So we asked him about it. The result was a series of blog posts for hbr.org, which Pozen has here distilled into six principles for a more productive work life.
