It was early 2010 when I wrote my first novel. And few months later that I finished editing. Then a few months more and I had the editing completed by another entity. Finally I was ready to be published.
I WAS WRONG!
My writing has improved considerably since 2010. I have read a lot on writing, editing, and then compared all this to novels I have read and to what I have written. I know my writing will never be perfect, but it is pretty good and the majority of people enjoy what I write.
What I learned was that it takes many years to become a competent writer that can also edit their work so that their writing is not riddled with mistakes. Not just spelling and grammar, but also over-writing, dialogue issues, cliches, over using adverbs, adding your own soap box into the story, repeating yourself in the next paragraph, plot spaghetti, and other things you will need to learn.
I have written since I was 10 years old or so. However, being creative isn't enough, you need to mould the story into something people actually want to read.
