This sixth edition is a thorough revision of our book. Each chapter has been revised for the purpose of presenting you, our readers, with a foundational understanding of entrepreneurship as well as with current examples of actions being taken by entrepreneurs and by entrepreneurial firms. We use insights from the academic literature and the experiences of practicing entrepreneurs to inform our explanation of entrepreneurship. To present you with specific examples of entrepreneurs actions and the actions taken by entrepreneurial firms, we again use insights from entrepreneurs as well as from business people. These insights from practicing entrepreneurs and their firms and from business people were drawn from many sources including podcasts, blogs, newspapers, companies' websites, and popular business publications such as the wall street journal and fortune magazine among many others. As we'll explain later in greater detail, we also draw from the academic literature to make certain that we are presenting you with accurate and current descriptions of what researchers have learned about successful entrepreneurs and effective entrepreneurial firms.
