We introduce, and empirically test, a model of entrepreneurial burnout that highlights the relationships among job fit, entrepreneurial passion, destiny beliefs, and burnout. Using a sample of 326 individuals involved in entrepreneurial jobs, we tested the link between job fit and two forms of passion—harmonious and obsessive—and the moderating role of entrepreneurs' destiny beliefs about work (i.e., the belief that a successful career is “meant to be”). Findings illustrated that their job fit perceptions were positively related to harmonious passion, which in turn negatively predicted burnout. Additionally, the relationship between job fit and obsessive passion was moderated by destiny beliefs, such that it was positive at high and average levels of destiny beliefs. In turn, obsessive passion was positively related to burnout. We discuss implications for both theory and practice.
