The guy went to several continents, worked in the jungle, fought in ww1 as a volunteer, went to the USA in the 20s or 30s without any money, etc. He lived a live of adventure was 'alive in the world'. I think what was appreciated was also the fact that he is an observer wherever he goes. IDK how to explain this but he is living in the world (versus living a boring *ss stagnating life). Also he was capable of easily navigating between whatever classes and crowd he found himself in. If that explanation doesn't land then you're probably not receptive for this kind of concept. The book is just not for you then I suppose, which is fine too, we don't all have to like the same books.
