One of the reasons Roald Dahl was such a great writer is his life experiences. Read his books Boy and Solo.
An example: a dyslexic friend and a dyslexic family member: their writing communication skills of both is now fine in part because their jobs required it from them (and in part because technology helps). I also had one illiterate friend, who has taught himself to read and write as an adult (basic written communication), due to the needs of his job. Learn by doing, and add observation of others as an adjunct to help you. Even better if you can get good coaching (which requires effort at your craft or sport).
Disclaimer: never a writer. Projecting from my other crafts/sports. Terribly written comment!
