On my window sill beside my desk I have no less than ten books on writing your first novel. This is not including the numerous articles I have on my hard drives. Included in this list are a few must haves - Strunk and White- Elements of Style travels with me everywhere. so does Stephen King-On Writing. The others while good reads- (and think about this, being a writer reading about writing has to be the epitome of procrastination) did not really further my writing or prompt me to write any faster. Now don't misunderstand, I am all for learning and honing our craft of word smithing. Many times that takes reading and learning and studying. However the best way I have found to get better at writing is-writing. So why do I have ten books on writing staring at me everyday? Well I bought those books before my first book was published and it was really a way to feel like I was progressing in my book without actually having to write. In other words it was busy work, but not real work. Very similar to shifting those papers around from one side of the desk to another but not really doing anything about them.
So here is my advice: Just write it- already.
You want to become better as a writer you have to write, a lot.
You want to become a published writer? It wont happen just thinking about it, only you can write your story.
By all means hone your craft, learn as much as possible. Read the books on writing, get the style guides. Just understand that at the end of the day none of that can replace your voice on a page.
