Even as a teacher, I don’t have to write much in an average day. In fact, the most handwriting I ever do at a time is in my diary. That’s probably why, whilst it’s not GP-level indecipherable, it’s certainly not ‘neat’.
But then, on the other hand, last time I checked I could type around 80 words per minute on a keyboard. This is due to me having used a program called Mavis Beacon Teaches Typing when I was about 12 (it came free on the front of a computer magazine). Its games-based approach made learning to touch-type fun. It didn’t take many hours of practice for me to become fairly quick.
