This chapter surveys the literature on the outcomes of passion in entrepreneurship. The findings reveal that passion is consequential not only with respect to intrapersonal outcomes (affect, cognition, behavior of the entrepreneur, and performance of their venture) but also for interpersonal results (for stakeholders such as investors or employees). These outcomes, however, are not always beneficial: although passion has been proven to have a host of positive outcomes in entrepreneurship, more and more recent studies have started to uncover its dualistic nature and detrimental effects. The review offers specific suggestions that will be instrumental in carrying out future research regarding the role of passion in entrepreneurship and specifies implications for entrepreneurship practitioners.
