Lot of very interesting advice, but I think it fails at its stated goal of "How to get rich without getting lucky". Much of the advise is extremely hard to follow and implement. For example, how can someone reliably "arm yourself with specific knowledge" if "specific knowledge is knowledge you cannot be trained for"? This is very hard to pull off, and most people will not succeed at this, even if they work very hard at it.

Here's a much more reliable recipe for getting rich: Study your ass off in school. Do whatever it takes to graduate with a stellar GPA, and letters of recommendation. Attend the best University you can get into, with above credentials. Pick a major with a proven track record of financial success, such as Medicine/Software-Eng/Accounting etc. Get a job at a brand name company. Continue working your ass off to impress your manager and colleagues. Switch companies every 3-5 years, to maximize your compensation.

You're not going to be featured in any newspaper if you follow the above strategy. But you can certainly become a multi-millionaire, even in your late 30s.
