Arrogant, just based on the fact he absolutely refuses help and not really well prepared for his choice. It's like he assumes that some of the authors that he idolizes and sort of did the same thing he is trying to do the whole "I' gonna abandon all my possessions my family and friends and money and live off of the land" deal but one thing he may have disregarded is the fact is that they only did the "living off the land" thing for only a few weeks and possibly a few months at most.
The concept of not adapting to social conformity like the whole not liking to wear socks when he worked at the McDonald's at Bullhead City.
Well one idea that comes to mind would be relating to an episode of south park episode entitled Chinpokomon where the boys become absorbed into a japanese cartoon and in the end they have to decide between individuality and conforming to go along with the fade.
A connection between me and the book would be that I do enjoy the outdoors and camping but not to the degree that I would abandon my entire life just to live out in the woods and eat twigs and berries and stuff.
I suppose a connection that the book can make to the real world would be that we all have a certain desire that we all wish we could leave our current lives behind us but we either feel obligated to our situations or we don't feel that we could pull it off
