>>823207I hope you read lots. Lots and lots.
Whenever someone asks you how your writing is going, and you're reading, say "I'm doing research."
Take quotes from your favorite authors and dissect them. Change the word order. Better? Worse? Write something the way that author would.
You can't compose a symphony if you've never heard one. You'll write better with the inspiration, too.
Sorry I don't have any online courses for you. Nobody can teach you to write well, you have to learn to do it alone.
