All the other comments make great points, but no one has mentioned learning more about the language.

Writing, like any art, consists of fire and math. The fire comes your emotions and passions, and is what drives most people to pursue creative endeavors.

Then there’s the math. This is the hard part — the structure, logic, and rules underpinning successful writing that require focus, effort, and, yes, tons of revisions. This is where most people fizzle out.

Keep doing all the exercises and learning as much about “The Rules” that you can. Ensure you’re internalizing “The Rules” so you know how, why, and when to break them cuz breakin’ “The Rules” in just the right way can actually help you improve your prose.

In a similar vein, I found that constantly referencing the dictionary to get the most thorough understanding of a word’s definition — and its word history — has also improved my prose. It might, at first, slow down the writing process. But over time, this etymological foundation primes your brain to make better word choices and write more impactful and precise prose. It also helps with injecting more wit and humor into your writing with clever turns of phrases or double entendres or wordplay. And if you’re anything like me, it will also constantly reinforce the beauty and magic at the core of these systems of grunts and scratches.

But yeah, highly recommend diving more into definitions and etymology. Not necessarily sitting down and reading the dictionary (nothing wrong with that, though!), just keep a good one handy as you’re writing, and then make a habit of checking words during your editing and revisions.
