Don’t be afraid to change your work. When you finish your ‘last’ draft and hand it out to BETAs, their comments will probably reshape your work (for the better), and then, when it’s polished like diamonds, the eventual edit before publication will reshape it further.
So don’t be afraid to change it, your work needs to continue to flourish. Change is universal. Just be mindful with your works’ transformations!
If I say this enough it’ll really stick in my head. X3
