Cal Newport, Professor at Georgetown University, has written a new book called, "Be So Good They Can't Ignore You: Why Skills Trump Passion in the Quest for Work You Love," which effectively argues that following your so-called passion to find the perfect career is a myth - and even potentially destructive. Cal talks with Tim Muma about what truly fuels a successful and satisfying career, why our pre-existing passion often fails, and a few tips on moving in the right direction to a better, happier career.
