A well-cited 2003 study of college students at the University of Quebec by Robert Vallerand found that they were more passionate about sports, arts, and music than anything they were studying. Unfortunately, only 3 percent of all jobs can be found in the sports, music, and art industries. And just because you’re passionate about, say, tennis doesn’t mean you can become the next Serena Williams, no matter how hard you try. “Follow your passion” is irresponsible business advice.
