I find my motor skills very variable, it depends on how much attention I'm paying, and oddly, is often worse the more attention I pay. I can move pretty fluidly when I've learned to make something a muscle memory (playing musical instruments and typing, for example.) But, if I have to try to think and focus to perform the action, I fumble a lot. I was often called "cack-handed" as a child (my Dad's favourite word for it.)
I seem to have very wonky proprioception too, which doesn't help - it's not unusual that I try to move a part of my body so that it would have to pass through another part of my body, because my brain has lost track of where some parts of me are. Copying other people's movements, I find extremely hard - I was terrible at sports because I just couldn't follow the demonstrations, and my drill instructor in Boys Brigade gave up trying to get me to march smartly in the end.
