I am mixed-handed, or cross-dominant - I do some things with my left hand, some with my right and some with both. I could probably become ambidextrous if I made more effort to learn skills with both hands. When I try something new I have to check which hand is best as sometimes I find I've been using the wrong one and the other is better.

And yes, I am disorganised! I make mess all the time even though I don't actually like mess. My house is a tip. I had no idea it could be connected to this.
