Writing anything using a keyboard is successul for me as I have fine motor control issues which result in handwriting that is illegible and not just for readers but for me. A Jackson Pollock drip painting is more legible. I never write anything. Even my weekly shopping list is typed (albeit into Apple Numbers)! Because not only do I have dyslexia — the fine motor control is a facet of that — but also dyscalculia which means I regularly mix up digits. If I can get away without having to transcribe numbers I will. And these days I make much use of the OCR features in macOS, iOS, and iPadOS to get around from copy-typing quotes from books or journal papers.
I will never ever revert to using pen and paper — other than to put a tickmark on my repeat prescription coupons.
