Looks like this guy is trying to run a lifestyle business, and his investments pay enough interest that he can coast for a long, long time. To be quite honest: He's spending all day playing . That's a position I envy quite a bit.
I'm not sure I understand this attitude. There is a specific lifestyle he is trying to achieve and the is working towards being successful at reaching it. At what point does it stop being "playing" and become just living? Do you have to be miserable at a 9-5 job to be considered serious by society?
In a sense, it's cool, cuz like, you're helping people in the world out for less than the cost to provide that service. But in terms of recommended reading material for people hoping to replicate the situation without an infinite runway, selection bias is a definite concern.
