Have you ever started a book, and then later wanted to change it completely?

YES.

I think this is normal for a writer.

To create is to be vulnerable. So sometimes you want to keep making your writing as perfect as it can be, but in reality, you have to learn when to edit and when to say that your book is the best you can make it.

I think that having really good beta readers can help with this. Other writers or readers who essentially “get your story” and understand the heart of your writing can help you know if you need to change something, or if you are just being an author who simply cannot stop changing something.
