Hello! I just had the realization my original plot just isn't going to work but I'm almost done with my first draft and I'm too married to a lot of my scenes I've already written to feel like i can fully start over. Do you have any advice? Just thinking about starting over is making me want to put the pen down for a while...
Starting over near the finish line
By first draft, I'm assuming you mean that this is the first attempt at putting the your story to paper. What I'm about to say is not to devalue the incredible amount of work that you must have invested up to this point. It is an accomplishment on its own to sit down and put words on that page, let alone reach a point anywhere near a finish line.
The first time you do something (anything) is rarely the time you do it well, let alone perfectly.
If I sat a beginner down with some printouts of blogposts about knitting and a spool of yarn, I doubt they'd make me a sweater without having to undo at least 50% of the moves they make. That wouldn't be because they're stupid or genetically predisposed to suck at knitting. Regardless of how seasoned you are as a writer, each work you approach is like starting a brand new hobby from scratch. You have to mentally allow for space to make errors and to let go of good ideas. This doesn't mean you throw the good and essential core of your story out.
Take significant time to review what you have, identify the bits and characteristics that you find most emotionally and mentally compelling. Write them down, examine the commonalities and congruencies between them, and work out exactly you like about your story as it stands. There is always good amongst the bad. You seem to already have identified certain parts that you cannot bring yourself to let go, so once you figure why that is, you'll be able to trim away what doesn't serve you and move forward.
You aren't starting over. This is not the beginning, and you will never be back at the beginning again. This is process, and process is imperative to making anything. If you continue to visualize writing as an act that starts at point A and ends at point B you will never be done. Nor will you do justice to your ideas. If you don't allow them to waddle around and fall on their face like the newborn babies that they are, they won't develop as they're meant to.
This is not failure. This is writing. It's a necessary part of what you're doing. It's normal. It's good for you. It's good for your story. In fact, it speaks well to your character development and world building and even your plot development that you can recognize there is so much worth salvaging in this first attempt to bring to the next. You're already emotionally connected to so much of what you've made, and plot is only part of that. If you're able and willing to acknowledge what doesn't work, you will be able to trust yourself when you determine what does. A story is a sum of its parts, and this is just one part that you're going to put down, regroup, and reconfigure.
There are several resources that I've created over the many years to assist in plot development and all the problems encountered within, and those are available on my masterlist for your perusal.
I wish you the best of luck and look forward to your triumphant follow up once you finish that second draft.
