I hated trying to decipher someone else's script. My Mom's script is particularly difficult to read.
I had horrible script handwriting myself .
On the other hand, once I learned to draft, and worked in the industry for a few years, had excellent block letters, and it was almost as fast as writing script.
I wrote everything in block draft after that.
I even learned to draft left-handed when I almost chopped off my right arm in a motorcycle accident.
It messed with my brain a bit to have to work with the opposite side, but I got pretty good at it.
As far as spelling goes, I was raised mostly in the pre-computer era, so I rarely have spelling errors, but still spell-check everything.
I wish some of the kids on FR would hit that "Spell" button more often, as it annoys me when I see horrible spelling errors, and denigrates their posts.
Same for me, I'm a draftsman and have been for over 30 years but I haven't been on the board for about 12 years. My lettering still looks good though. I'm amazed at some people's handwriting and how they ever got through school.
