I notice that I mostly look at my left hand while I play the piano. I don't know why I do that, but if I'm gonna look at my right hand, like I do at my left hand, my left hand mostly makes an error. Is there an explanation for this? And I guess I should start working on this to avoid more problems in the future. The problem with this is that I sometimes can't remember what I play with my right hand. I can play it, cause I know where to put my fingers, but I mostly don't know what I play with my right hand, if you know what I mean.
