Want to be really, really wealthy? You can either inherit it or make your own fortune, suggests a perusal of the Forbes world billionaires list. Your chances of wealth almost beyond the bounds of avarice isn't likely to happen working for someone else, even if you're CEO of a major company (not that it hasn't happened to some), and you probably already missed on finding the right parental deep pockets.

Below are the most monetarily successful entrepreneurs in the world. To make the list, not only did someone need pockets deeper than the Mariana Trench, but had to have started the businesses that created their financial state. So while inheriting the family company and expanding it on a global scale might be an indication of great business acumen, it doesn't make someone an entrepreneur in the sense these people are. That omits many from the overall list, including some who worked their way up through various jobs and companies to run a large corporation. But then, the real entrepreneur's life isn't for everyone.
