Oftentimes in speaking with writers, I find that editing is perhaps--shall we say--not their favorite phase of the process towards a finished manuscript. This does not baffle me at all. Editing is often a massive undertaking, depending on the writer in question, and at its most extreme involves multiple passes, inserting and deleting scenes, redrafting entire chunks, and changing every other word to what will hopefully be a better word.
If your process does not require you to have everything just-so before you can move on, or you are already planning on incorporating editing, or you subscribe the 'garbage first draft' methodology, you will be editing. To avoid bogging down, I suggest reframing the challenge. Rather than viewing editing as big and scary, consider the question: what type of play do you like?
Personally, the answer to both 'how do I view editing' and 'what kind of play do I like' is the same. I tinker. Words on a page can come in an infinite number of combinations, and some combinations provide more oomph than others for my purpose. I like fiddling with words, testing them, considering how all the little moving pieces function together, and gradually refining until I have a working bit of writing. For me, that's what editing embodies. I enjoy it, because the process of incremental discovery feels like a series of small triumphs.
Depending on the kind of play you like, consider incorporating some of the principles into your writing and editing process. If you like playing with strategy, you might be an outliner up front and an editor who hunts down cause and effect in your story until you've executed a masterful plan to take the reader from opening gambit to the final climax. Or if you enjoy, say, FPS games that depend on skill and game-sense, then your process might be about learning what hits and misses for your intended audience. For this, editing becomes something of an exercise in target practice as you learn how to smoothly calculate your angles and line up your moments by going over your initial, instinctive picks.
Metaphors of how you like to play can be be extended to cover your writing and editing process, and incorporating some of the elements and patterns that you find the most fun in other areas of your life can make the prospect of editing much less terrifying.
