According to a 2016 LinkedIn study that analyzed its members' job histories, the average millennial switches jobs four times in their first decade out of college. Their restlessness can be chalked up to a bunch of factors—diverse interests, numbing routine, unnatural stress—but it might also have to do with an ardent belief: that by testing out enough options, they can find their passion.

Bill Gassen, chief HR officer at Sanford Health, believes that everyone should stay open to the possibility of a career change. Look out for those aspects of your current job that most inspire you, and let your passions guide each further step.

In this video, he tells his own story to explain why: Gassen didn't start as an HR professional. In fact, it was through his experience in another field that he was first exposed to HR, and that lucky coincidence has defined his career.
