Entrepreneurship is simply inserting risk between yourself and your profit goals. Having a job is risky enough. I heard Mark Cuban say having a job is like being self-employed with one client. I loved that, but back to the risk. If risk is between yourself and your profit goal, then surely the most pure form of individual entrepreneurship is being a commission-only sales person. Real estate has long been a highly sought out commission-only sales opportunity, and it is probably followed by “Financial Services.”
