Is it normal to always mess up writing?

If I'm physically writing something down, I can never write it correctly the first time. Even just a short note, I always mess something up, such as misspelling something, accidentally writing the wrong letter, or leaving a word out. Everything I write is full of things scratched out and rewritten, it looks so horrible and I get lost in all my scribbles, throw it away, and try again so that it's neat.

I've never had a real problem with dyslexia or anything like that, but why do I always mess up? Does anyone else do this?
