Is "Following Your Passion" Bad Advice?

"If you're twenty-three, in your first job out of college, not yet that good at what you do and starting to wonder if maybe this isn't your true calling, or if you're nineteen, and thinking about switching your college major because you don't love every minute of every class, and worry that a "true passion" should always feel inspiring: I suggest taking an hour or two to watch some episodes of Rowe's show." - CalNewport.com
