The best you can do is the best you can do. There’s a fine line between learning from other authors, and trying to be them. Be yourself. There are more than enough different types of readers out there for us all. I can’t tell you how much time I have wasted wishing my work were more “hip” and “edgier.” And every single moment was indeed a waste of time. I didn’t even like much of the writing I wanted to emulate. I just liked the attention heaped on the people who wrote it. Write the book you’d most like to read – not the one you think will win over the editor du jour.
Excellent advice. Take it to heart. Your writing is YOU. In the beginning, you won't sound like "you" when you write. You're self-conscious, and it comes across in your words. Over time, you will become "you" in your writing. No need to struggle. Just do the best you can to get your thoughts and ideas across.
If you're writing fiction, do the best you can to entertain your readers... That's all you can do. It's also all you need to do.
