Most have heard of "dyslexia", which to varying degrees affects many people's ability to read. My problem is a closely related, but much rarer one called dysgraphia. I cannot write a smooth, continuous sentence without having to stop and think what the next letter should be every few letters or so. I had to give up cursive for block printing many years (decades) ago. It also affects other repetitive motions, such as music. I hear music in my head, but as soon as I pick up a guitar or sit down at a piano, it all flies away.
