Choosing a career path is a big decision. In the modern western world a career is practically synonymous with identity: whether we like it our not, what we do is a big part of who we are. And we are told to choose a career carefully, to find and follow our passion. But what is passion in this context? And why should we follow it? Does following passion into a career path leave us happier? Leave us on more sturdy footing in our life and career? Who gets ahead and who gets left behind when we all chase passion to the exclusion of other considerations? We talk with University of Michigan Sociology Associate Professor Erin Cech about her research and her book "The Trouble with Passion: How Searching for Fulfillment at Work Fosters Inequality" to better understand why and how passion has become the primary decision-making point in chosing our career paths, and where that choice can lead us - individually and collectively - astray.
