It seems like a trivial yet cruel little joke that my lifelong love of pens and all things stationery has been accompanied by handwriting so terrible that sometimes even I can't read what I have written...
Ack, now I want to see scans of your handwriting, dammit!
I was going to suggest learning architectural lettering as well but I can't find any good way to learn it anymore. I think I was the last class coming through to learn hand drafting. BTW - my lettering is pretty good but my handwriting remains abysmal. The two are not necessarily the same skill.
I'm in a similar boat, coupled with a dearth of excuses to write this in pen and ink.
I use bullet journalling as my task management tool, so I do a fair amount of writing in a day. I also have lupus, and experience a cognitive issue called 'lupus fog', so I'm a copious notetaker in meetings and so on. It's just a shame that all of that activity doesn't lead to something I'm ever pleased to look at.
