Can you make — or “make over” — an entrepreneur? It’s a question that came up a lot as my co-authors and I researched our new book, Heart, Smarts, Guts and Luck. Those are the four traits we deemed crucial to entrepreneurial and business-building success. We even came up an Entrepreneurial Aptitude Test to measure how company founders and business builders stacked up in the different traits, and to help you identify where you’re strongest.
