Ask HN: How can I improve my writing skills?

I want to get better at writing clear and short sentences without making grammatical mistakes. I'm a developer and I think this particular skill can help me communicate better with my team / users by writing better documentations or describing any problem.

I keep iterating on the things I write and never seem to be satisfied, and see there is always a room of improvements. I don't feel the same way when I read others articles / blogs.
