Not writing as much as before, but still writing the occasional card and such, I one day decided I would try to improve my cursive writing. Not doing any extra training as such, I just started to write a little more slowly and at the same time I made the letters a little bigger and made the loops larger for letters like: f,g,h,l etc.
Looks like it has been working out for me, as one day my nephew said: "You have a nice handwriting". I smiled to myself, and thought: "You should only have known". I savored the moment and kept the trick to myself like an old magician. Will let him know though :-)
When I write fast and long (seldom), I need to concentrate to keep the letters looking good; but at least I know now that 'I am not just a bad handwriter and that is just the way it is'. So take hope! :-)
