Drum roll, please. Today, #17 in our countdown of the top 22 books of last year: “Humor, Seriously: Why Humor Is a Secret Weapon in Business and Life (And how anyone can harness it. Even you).” For years, Stanford professors Jennifer Aaker and Naomi Bagdonas have been researching the benefits of having, and cultivating, a sense of humor.

To learn more about “Humor, Seriously,” visit humorseriously.com.
