If you haven't touched a pen for a while - do it. Doodle something, write notes - do not let the skill of holding a pen get away from you. By not using a pen, you can cause regression of this skill and might end up being surprised how hard picking it back up can be!
(Inspired by people who apparently couldn't remember when they last held a pen, whined that it hurt their hands, and said it was difficult to write a SINGLE PARAGRAPH OF TEXT. Don't be like them.)
