Cal Newport's advice is more along the lines of "Do what you're really good at, rather than only what you love."

That's interesting, as other career gurus argue the opposite view. For example Barbara Sher, author of "I Could Do Anything If I Only Knew What It Was" gives the example of herself as an unhappy stay-at-home mom. She is an expert at cooking, changing diapers, and other aspects of child rearing. If she pursued what she was really good at, she'd be limiting her options to work as a nanny, or perhaps open a day-care center.
