Alright. So, as usual, I kinda have a hard time placing myself in a category, because I’m sort of everywhere at once.
I am traditionally right-handed, but there are certain things that I do far better with my left hand, and recently I’ve found that the two are naturally balancing themselves out for whatever reason. In addition, a lot of the things that I do with my right hand I’m not good at with my left simply for, it seems, lack of practice; my handwriting with my left hand can, for instance, be easier to read then my right-hand handwriting, but it takes far longer to write.
I find this all rather odd, since I used to be exclusively right-handed, and wasn’t much good at using my left hand for much of anything. As I’ve gotten older, though, the two have, as I said, been balancing themselves out on their own. It’s a strange thing, but certainly not unwelcome. I’ll take another good hand any day. 
Additionally, I’ve always been known for having really balanced hemispheres; I’m both highly logical and highly creative. For instance, I love to write science fiction, because writing is one of my favorite activities, and also one of the most natural for me, and I can’t get enough scientific info to be satisfied no matter how hard I try. In the creative realm, I usually write poetry and fiction on my own time, as well as play the guitar (I write all of the music I play, too) and create visual art both by drawing and by using my computer. A lot of these disciplines blend into one another; I write all the lyrics for the bands I’m in, as well as composing the tunes for them and integrating them into the rest of the music and my guitar playing. I absolutely love creative pursuits, and they constitute my main form of entertainment; if given free time, I will typically begin creating art prolifically. Once I get an idea for a new creation, I generally can’t let it alone, and have to bring it into existance before I can be satisfied.
However, as I said, I am also highly logical. I am reknowned among those who know me for being an excellent debater (if someone who doesn’t know with me disagrees with me on some topic, those around who do know me will frequently warn them as to what they’re getting into
), and my analytical essays are well-respected by both my peers and those above me in the social hierarchy. I delight in complex mathematics, and can talk for hours about scientific theory, in just about any area (though physics and biology tend to be my favorites), and my personal philosophies and beliefs are based entirely in logic, to the greatest extent possible.
So, as usual, I’m an odd anomomly who’s too ambiguous to really prove anything. It’s impossible to discern from my propensities, skills, and behavior whether my handed-ness has anything to do with my other personal attributes, since both are highly expansive and/or inclusive, but I’m something of a curiousity nonetheless. Here’s to being the all-category-fitting skeleton key!
