I love writing by hand <3 I learned how to use a physical planner as an adult because I found out I really could not "see" or keep track of digital calendars. My handwriting in those is uniform and deliberate because if it is not I will have no grasp of time or task management. I don't fuss too much when I get a little messy, though, because I have to constantly exercise my ability to refute perfectionism. If it's readable, it's workable. And sometimes it's good for me to switch up my writing style- I did a month in cursive because I realized I wasn't actually taking in the words on my planner anymore so I had to make myself work harder to do so. I also switch pen colors every month to keep me focused.
uhhh all that to say- I hand write a lot, every day! Like, yeah, I constantly type thousands of words of fiction and notes and chats, but I think handwriting is a very important skill to have and a good exercise for both brain and body. Especially when you consider that spelling also tends to go downhill with easy access to spellcheck! I also still do a lot of math by hand because it's more fun that way. It's just a little puzzle. :)
