Some extraordinary and unexpected factors are revealed in Taylor's fascinating new book that explains why some people become billionaires. Despite the fact that the sample of 17 self-made billionaires come from disparate backgrounds, work in different industries, have very different personalities, and superficially appear to have different upbringings, they have one important thing in common: they are all outsiders. Their edge comes from being different and that difference is the well-spring of their creativity and wealth. This combined with direction, drive and trading intelligence has powered them to extreme wealth.
