I enjoyed Martin Fridson‘s book of that title — with the subtitle Proven Strategies from the Titans of Wealth.
Fridson’s method is to study those who’ve become billionaires to isolate common traits and actions. Ross Perot, Bill Gates, Sam Walton, H. L. Hunt, Warren Buffett, John D. Rockefeller, Wayne Huizenga, and others get careful (and sometime amusing) attention. Taking monumental risks, thriving on deals, and doing business in a new ways are recurring themes.
Majoring in philosophy does not seem to be a common path to riches. Until we get to this reassuring anecdote about Carl Icahn, the high-flying takeover artist:
“Philosophy major Carl Icahn took first place in the annual judging of Princeton senior theses. His topic was ‘The Problem of Formulating an Adequate Explication of the Empirical Criterion of Meaning.’ You may have to take his word for it, but the famed corporate raider claims, ‘In a funny way, studying twentieth-century philosophy trains your mind for takeovers.'”
Excellent.
