This research note explores the differences between habitual entrepreneurs (serial and portfolio entrepreneurs) and novices in terms of their passion for entrepreneurial activities. Using the Dualistic Model of Passion as a conceptual framework, the hypotheses were tested using a random sample of entrepreneurs that registered a limited company in 2008. Results of logistic regression analyses showed that habitual entrepreneurs experience extra high passion for entrepreneurial activity. However, of the two passion dimensions proposed in the Dualistic Model of Passion – harmonious passion and obsessive passion – the obsessive component is particularly evident among habitual entrepreneurs. A closer analysis, comparing novice, serial and portfolio entrepreneurship, suggests that portfolio entrepreneurs score highest on the harmonious dimension of passion.
