I'm an artist by trade, typically I write in a way that pleases me aesthetically. I'm not someone with "scruffy writing", but that also backfired when I developed a cursive style that felt nice to write but took longer to read than a bunch of capitals. When I stopped needing to write for school, where they teach fast cursive, I spent another 12 years on and off in some form of academia so I needed to write fast for note taking, and ended up using my own shorthand... but the issue with my shorthand for me is if I spend any time away from it it becomes harder to read when you go back to it. If I go back to my old notes now it looks like Arabic to me.
Caps have been better since being an artist and not needing to spend so much time writing by hand. A bad thing, tbh. Going back to writing now after years with a keyboard makes me feel like I've lost some aptitude for it. I hate becoming worse at anything.
Most mens' writing I see looks tiny, spidery and/or half legible. Most women's writing I see is too big and takes up too much space and ink.
