Why is it wrong for me (or anyone) to get fulfillment out of their job? Thanks to my partner I do the traveling thing; I visit other countries, sample other cultures, and routinely try new things. I'm not averse to any of it, but I don't understand the appeal, much less (what I read as) the condescending attitude against people who don't do it. Why can't we just "live and let live", without judgement, even if others choose to live differently than ourselves?
