Wait, where did my life go?
Sometimes I think about times I spent playing games and it seems like such non-achievement, so far from being anything real, that it's like big chunks of my life just gone for no return. All those times I killed ten Fozzbears and three Greater Fozzbears in Wow so some dude with a questionmark over his head could tell me to kill ten greater Fozzbears and three Dire Fozzbears, well, in retrospect that time could perhaps have been better spent. But then the time I played right the way through Quake on co-op with three friends, that was pretty much awesome.
I guess it comes down to what you want your life to have been about when you look back on it from your deathbed- do you want to count your achievements in the wider world, whatever their magnitude, or how many Dire Fozzbears you did away with and how epic your mount was. It doesn't really matter which, as long as you can have your expectiations set.
