Best Writing Tip for a Newbie

Last time I dabbled in fiction writing I bought a couple dozen books and read them all. Imagine how much actual writing I might have gotten done if I spent all that time actually writing. This time around I'm trying to limit reading so much about writing and just DO IT.

Yes, I'll make mistakes. Yes, I'll use the wrong punctuation. Yes, I'll slip into bad grammar. Yes, yes, yes...but that can all be fixed during editing. I'm realizing that I have to just write when I can, when the mood hits, and even when I don't feel like it. Maybe it won't be on my novel, maybe it will be a short story or some flash fiction. That's okay, it all helps to improve my style and voice.

So, give my YOUR best tip for a newbie writer....
