Making it onto the list above undoubtedly takes many years of hard work and persistence. In a league of their own, Gates, Slim Helu, Buffet, Ortega and Ellison have been leading figures in their industries for several decades. However, great work does not always translate to fortune
. The people in this list have made it to where they are by recognising opportunities that others missed and having the necessary business acumen to capitalise on them.
