Dimitry! Don't shut him down, how mean!

haha, just kidding.
I'd have to say the most common thing is jealousy. At least, that's what it's been for me.
Another thing (for me) is mediocrity... I can't stand that. If I've been w/someone for awhile & they don't seem to be going anywhere... that makes me INSANE! Like...just workin at a little store of some kind, never thought of change, & happy in that piss ant job... No good.

BUT, I'm gonna have to think that's just me, cuz I'm just mean like that.

:o
