What a fantastic questions @Jeff! What came to mind first is COURAGE. When I started my business, non-entrepreneurs asked me so many questions that showed their own fear: "Aren't you afraid you are going to lose money? Aren't you afraid you might fail? Aren't you afraid you might lose everything?" Fear, fear, fear. And NO, I wasn't afraid of those things. I was convinced that I would succeed because we were going after a very real problem that wasn't being solved. I woke up every day with hope, not fear. I think that was a big difference in mindsets - my friends who were entrepreneurs never asked me those kinds of questions.
