I have been doing a lot of editing to various drafts of various books I have on the go at the moment and one of the biggest problems I face is keeping motivated doing the editing so that I am actually doing something constructive to the work and not just reading it to pass the time.
Editing your own works is hard, you wrote it and for whatever reason those words are on the page in that precise order that you put them, so reading it back and trying to cut out that which is not adding to the story is difficult. Otherwise you wouldn’t have written them in the first place.
But I know that there is always something that needs to be done, finding the odd blind alley, character or plot inconsistency, wrong words, typos and so on. This makes the task very energy sapping because you have to study every word of every sentence and justify its existence.
I have a mantra that I am using as part of this process “does it add to the story? does it add to the story? does it add to the story? if not cut, cut, cut.
it is a hard thing for me to do, but I know it is needed. Writers need to be brutal when editing.
