On the other hand, your perspective is shaped by not being dismissed by the vast majority of the people you encounter for that shortcoming. I would imagine you might feel very differently if every person you met treated you as an imbecile because you were't articulate enough, especially if your best efforts at improving don't move the needle much.

I can't speak for the OP's experiences, but my early schooling years were marked by receiving a number of marked down or failing grades because my handwriting was awful, it still is, but at the time no matter what I did, I couldn't get my handwriting to stay neat. Writing neatly was too slow for my thoughts, and I'd get lost or go off topic. But writing at a pace to keep up with my thoughts turned my writing into barely understandable runes at best, and incomprehensible scribbles at worst. Even where handwriting wasn't supposed to count, I lost credit because of how bad it was.

At a certain point I was given permission to type all of my work. Even for tested material I was given proctored access to a type writer (and later computer). And my grades improved noticeably. My subjective experiences and enjoyment of my written school work also improved noticeably. Maybe I could have spend more years working on improving my handwriting and getting it to a place where I was just barely adequate enough to stop losing credit for it. Maybe I have lost something "essential" about being human because my handwriting is still so bad I often can't read my own scribblings. But I am infinitely grateful to have lived in a time and place where personal access to typing systems allowed me to be more fairly evaluated on what I had to say, rather than how I could physically write it.
