One of my mentors was an absolute business genius, who around the first dotcom bubble built many many products, many that were very successful. Then around 27 he started going pretty wierd, and 10 years down the line it turns out he's paranoid schizophrenic, and either takes drugs which greatly dimishes his energy and smartness, or he goes crazy. Many of the crazy money spends and similar of Hsieh sound familiar, it's like the genius just gets more and more wacky ideas until they both get exploited but also destroy themselves. It's such a crazy story for me personally. There's also so many of these around. There's something about genius up until about ~27 years old that then can go completely insane. Seems to me to be linked to the whole 27 club [1] too. Seems like something really changes in our brain chemistry around then.
