That is according to your definition of "living life and being happy". The person in the article is clearly happy and has found his place in the world that he's happy with. For that, he has found the thing most people miss out on or just don't get. Leaving home just for the sake of it, more so if you're just happy wherever you are is just wasting time.

I would like to travel the world because that would give me the happiness this person has found just by staying where he is. That doesn't mean he should change his way because my definition of being happy is different that his.
