If this isn't a spam question...

There are basically 3 ways to get better at writing:
1. Read.
2. Practice writing.
3. Learn the technical side of good writing.

For reading you can read anything and it's actually a good idea to mix both fiction and non-fiction. Obviously if you want to get good at writing one particular thing, read more of that.

For practicing writing you just need to write - a lot. Some of it will be rubbish. Some of it will be OK. Some of it will be amazing. The more you write, the more people read, and the more feedback you get, the better you will be at writing.

For the technical side you can hope on any learning platform like Udemy and go through a writing course. Pick one that matches the genre of what you want to write about and then go through it. You'll learn the dos and don'ts, how to structure your pieces, how to properly edit, research, proofread and everything else.

I personally like Dr Clare Lynch's courses on Udemy.
