A while ago, I decided to learn to type with 10 fingers, rather than 2 (two index fingers).
I followed a strict prescription of how to place the hand, and where to place each finger, etc. I learned how to type with 10 fingers, which has significantly improved my typing.
Now I am considering to also improve my writing efficiency/effectiveness regarding the more ancient art of written words (pen and paper).
Is there some method, some set of prescriptions for how to place the hand and move the fingers, for writing neatly, clearly, and quickly with pen and paper?
