Just an observation from experience. It hasn't affected my rosy outlook on life. I try to like every person I meet and manage to find some reason most of the time. However, dealing with the public at large, and especially in a professional setting is a different matter. Don't you find incompetence, undeserved, unrealistic self-importance, self-entitlement coupled with an astonishing refusal to accept or take responsibility everywhere you go? I do. I expect incompetence with every organization and person I deal with every day. I love the rare occasions when I find someone who knows what the hell they are doing and what they're talking about. It's like a lovely flower blossoming in an expansive, dead and dying field. I cherish those people. Otherwise I have to expend more energy making up for the slack in those I'm dealing with. I don't become frustrated or angry. I become privately amused as it's exactly what I'm expecting. That's western society at large and I've encountered this same phenomenon more or less in every country in which I've travelled. I'm talking about objective facts and actions.
Cordial discussions about subjective matters are completely different.
So while I'm here, hail JLibourrel, well met!
