The more effort one ploughs into one's company's success, the more enthusiastic about one's own entrepreneurial activity one becomes. Experiencing success on a regular basis and the the possibility of free choice are two factors that play an important role in this context. These are the findings of a research project led by the psychologist Prof. Dr. Michael Gielnik of Leuphana University of Lüneburg, recently published in the Academy of Management Journal. The findings refute the widespread view that dedicated entrepreneurship can only evolve from a pre-existing passion for entrepreneurial spirit.
