I think there are two competing schools of thought and neither is completely right or wrong. One believes that an entrepreneur needs to serve a cause and do something to better the world and success will come proportionally to how much they have enriched others' lives. The other believes that an entrepreneur just needs to make a boatload of cash. There are countless examples of successful entrepreneurs that pursued both routes, but I do believe that those in one camp probably wouldn't do well if they tried the other. Some people are just very smart, and sometimes smarts, hard work, and some luck is all you need.
