Hi
You sound exactly how I feel mate. I think it's good you've realised early, some of us just go to a different drummer if you know what I mean. The rat race and **** if just a game created by man in essence, there's nothing natural about it, so for it to be the norm is quite startling. The fact that people work their ass off and then spend like 12 grand on a new car is beyond me, and the same goes for houses and stuff, renting is the way forward!
I'd recommend reading "into the wild". It does put that sort of life in perspective and is quite illuminating.
I do think however that having lots of relationships would be great but you still have to try and create friendships and just to a deeper level, otherwise you may feel a bit lonely.
