I say, do whatever you feel fits best with your story. If you want to change the prompts, follow it partially, or not at all, it's all right -- the story is all yours, and I'm sure it'll still be just as interesting to see an unorthodox choice in the storyline. You might have to play fast and loose with the prompts later on if you deviate far from it, though, but that's allowed, if you prefer it.
Mutatis mutandis. Si non confectus, non reficiat.
