Ok, I didn't mean you literally have to become a psychopath, but that there are some parallels. I think if you ask people who built a startup if they sometimes felt like a psychopath, I think many of them will not say no. Some quick googling also gave a lot of articles, such as that even HN readers are more psychopathic than the average internet users. http://blog.statwing.com/starting-a-company-can-turn-you-into-a-psychopath/ http://blog.statwing.com/starting-a-company-can-turn-you-int.... I'm not advocating in any way that college students should try to become psychopaths in order to start a startup, however, I don't think there is value in excluding a correlation between psychopatic behaviour and building a huge company. In fact, I think the founder of the largest companies we have to day are pretty insane and not in a good way. I think this helps bringing to the company to traction, but like Ron Conway was saying in the "How to start a startup"-lecture today about fundraising, what he found most impressive about the AirBnb founders is that the bigger their company becomes, the more mature they become, but also the more humble. I think that's the mix of crazy and humility you need to build the most successful companies.
