The conversation between human and AI assistant.
How do I go about writing a good book?
Yes, I already have some characters in mind. But how can I make sure that their personalities are distinct and believable?
A good way to do this is to give each character a clear voice and manner of speaking. You can also try writing out their backstory and figuring out how that has impacted their current behavior and actions. Another helpful exercise is to imagine them in a variety of scenarios and see how they might react.
