One of the rare noncharlatanic books in finance. (from Antifragile: Things That Gain from Disorder)

I grabbed a copy of What I Learned Losing a Million Dollars, and I’ve since read it many, many times. For less than $20, this tool has helped me avoid multiple catastrophes, and I can directly credit its influence to roughly 1/2 of my net worth (!). The ROI has been incredible.
