This is awkward, you posted before I edited. To reiterate!
I have nothing more to say. Your outlook is so negative that you refuse give credence to anything positive, and you can't be swayed. You won't truly consider anything that doesn't support your views (although I'm sure you could accuse me of the same!) You don't even acknowledge the merit of attempting to improve the world or oneself. We're fundamentally different, and arguing gets us nowhere. In any event, I'll continue to do the work I can to improve the world. You will continue to believe that it's hopeless and a waste of time. At the end, we can decide which one of us had the better impact on the world.
'Twas a pleasure clashing intellect with you as always, though. Never stop thinking!
