I use my left hand mostly, but I bat righty in baseball. I'm very good at drawing and I'm very artistic and creative. However, there's a misconception that lefties have bad handwriting, that's not true. I have very good handwriting. Even better than some right-handed people out there. I don't care if the ink or anything else smudges, because I use hand-sanitizer. Also, I put a piece of paper under my hand sometimes to prevent smudging. However, I type using both hands on the computer and I hold the mouse in my right hand. (With my laptop, I use the left for the touch pad.) Also, with the DS, I use my left hand when holding the stylus. I can dribble a basketball with both hands, but have better control with my left.
