alt Hacker NewsI am similar. If I physically write a couple times a week, my hand adapts though. It's a skill like any other.
Fountain pens are nice too since you don't need any pressure.
My writing looks a lot better if I just force myself to slow down and be deliberate, but honestly it's a constant battle. I'd definitely benefit from practicing penmanship on it's own.
Worth mentioning - for a long time, I found my handwriting messy AND my hand would tire out. When I was about a teen-ager, I decided to write in call-caps, very clearly. I've been doing that for a long time now, and worth giving a try.
