Readers for the most part are here to read. Not help us improve. Nothing wrong with that and mostly it's all good. That's the big draw on GA, the interactions with others. It's brilliant. I love the comments readers leave.
But there really is no book or magic beans or contract with the devil which will make you a better writer. So how to improve?
First you need some talent for the written word.
Second and maybe the biggest thing is: Authors have to improve themselves.
It is lonely, hard and soul tearing work.
How do we improve?
We do that by reading. Everyday.
We do that by paying attention to writers we like.
We listen to our editor and beta readers. My editor, told me. He is skilled and has been writing for years. And i listened, and i worked.
And you write.
And write and write and write and then write some more. And you read your work and say, "Gah, that is shit."
It is not your child, or baby, it is your work.
And if your work is crap, you throw it out and you do it again.
That's how authors who want to, improve.
