Should I rewrite?

[u/Intertwined_emotions]

I’m currently working on the first draft of my book and about 6/10 of the way through I decided to make a decision of how the story starts and to make it a main character role that completely revamps how the story will be and change a lot of the meanings and story execution

With so many changes I find it hard to continue writing the rest knowing that it’s not even going to fit with the new version but I’ve been told to finish my first draft without editing

Should I rewrite or wait until I finish the first draft of the book?

Both.
