QotD: "Nothing Sharpens Sight Like Envy"

What quality in your best friend are you most envious of and why?

It depends on which friend we're talking about.

The one:  I'm probably most envious of his utter self-containment.  He is hermit-like and apparently comfortable with that.  It's very Aristotelian of him, and I envy that.  (I'm referring to Book X of the Nicomachean Ethics when I say Aristotelian).

The other:  So, OK, he's a bit of a dilettante, but he knows something about everything.  I mean, he's been in the army and achieved fluency in Spanish and Arabic along with some degree of ability (I'm not sure how much) of Italian and Slovene and then busts out with French or Scots when you least expect it--not to mention that he can insult you in Russian.  He's been a shipbuilder.  He brews his own beer and makes his own furniture.  He knows his liquor, he knows random things about beekeeping.  He is, wow.  I am in awe of the sheer volume and breadth.  It's really something. 

I wish I knew shit.  Alternatively I wish I could do the hermit thing, thereby hiding the fact that I don't know shit from everyone.
