I suppose that by hedonism you mean materialism, and I get your point. What I was trying to say is that it's tempting to believe that some kind of ancient wisdom could guide your life (indeed I'm sure Tim Ferris doesn't believe it himself, but some readers might).

It doesn't mean that there is nothing valuable in the stoics' writings, just that using these thoughts as a "Personal Operating System" is as useful as installing MS-DOS on a smartphone
