I think I speak pessimistically (though not too much because then I would just be a downer), think optimistically, and act realistically. I think I'm pretty good at helping people and making people laugh. When things go wrong I seem to get a call. And not because I screwed them up.
My day automatically gets better when I get in my car, put the windows down, music up and just drive. Also, when an old lady crosses the street in front of me, looks at my car, signs OK to me and nods in approval.
I've been described as a kind, caring, sweet person and not too long after that as a jerk, asshole, rat bastard...sometimes just regular bastard. Not like the "Oh, here comes that asshole." kind of asshole, more like your jaw drops and you crack a smile while calling me an asshole, kind of asshole. I seem to have good delivery when I joke around with people.
I use how others describe me because sometimes other people see things in you that you can't, not to digest that I'm not self aware.
