I think there's plenty of available advice on how to become ultra-rich. Just look at the Business section of any bookstore. The problem is that this advice typically takes you from a 0.001% chance of becoming ultra-rich, through sheer lucky accident or lottery, to a 0.1% chance, through strategy and calculated risks.

I'm not arguing that it's not really hard and really improbable. However, folks tend to assess P(becoming wealthy by any means) ~ P(winning the lottery).
