To try and help with my dodgy hand, I bought a small stress ball off eBay. Lovely, has a globe printed on it (so it is educational too!). I squeeze it with my bad hand, and compress it around 1cm before the tension defeats me. I must try to squeeze this every day. Certainly this isn't brilliant, I'm just hoping that one day I will fully compress this thing, and it'll help to remember this time and see progress.
