Honestly, handwriting is mostly just practice, kind of like art. The exceptions are generally medical sorts of things (including stuff like dyslexia). In that vein: Have you tried learning calligraphy? If you use the more traditional nib shapes (even if using a fountain pen), you'll likely form letters in a different manner than with a ball point pen. You can move from more traditional stuff to things that look like print or cursive that you like. And then it is just practice.
