“Proofread carefully to see if you any words out.” ~Dave Barry
You want to save money and edit your work yourself? Many writers do. I personally want you to know that editing is the single largest factor that separates the books published by a large publisher and a self publisher. It is the “tell”, it is the glaring thing that discredits self-publishing. So, if you have not combed over your work with a fine tooth comb, then you should because that is the one strongest area that could make or break your success. Now, I am not saying that it must be grammar perfection at in its highest form but I do mean to suggest that tons of little errors make your work weak.
Namaste,
