I've partly read Liar's Poker, I haven't watched or read Moneyball. Still, the part I read made me a fan of Michael Lewis. Here is a link to Michael Lewis's recent Princeton Commencement Speech.
I wonder how every commencement speaker has some dramatic narrative about his own life and how there always is a lesson to learn from it... always.
The lesson here the part of luck plays in your success. Old, cliched, but Lewis's speech makes it sound profound. I couldn't help thinking about Nassim Taleb's books - Black Swan and Fooled by Randomness. Same theme!
