Summary: As a man grows, he acquires knowledge and an understanding of the value of said knowledge. He also becomes aware of the value of people and wants to give of what he has so that it may be of benefit to them. This may come in the form of a new product, an online course, some free training, mentoring, or a service based business. But, I think entrepreneurship, large and small, is the natural progression of the growth of a man.
