I hope you like that one, it's one of the more interesting investing/biography books I've read in the last few years. If I remember correctly, there is a section where he talks about Bernie Madoff and when it was brought to them how he could tell the math didn't add up and refused to invest. If not the book, maybe I heard him say it on a podcast with Tim Ferriss. Either way, fascinating guy.

Thanks for the feedback on the Legion Bob book, glad you tried it :-)
