This is a bit more low tech, but you mention technique, and I think people should hand write things more. At least, for first drafts.
You neurologically process things in a different way when you use your hand in that manner, and the act of transcribing your own work into a computer or device is an incredible editing measure in its own right. It forces commitment and flow, which is so precious in our time of short attention and focus.
Also, its good to be fluent in both skills, because you never know what could happen to your body. Realizing you haven’t extensively used a pen or pencil much in years is a pretty fucky kinda feeling from a motor dexterity perspective.
Oh, I understand that. My handwriting isn’t great, and I used to do absolutely massive, elaborate drawings, dabbled in asian calligraphy, etc. those skills do not translate.
