The mistake
Explaining the same client in every new chat
Without a project, each new chat starts cold. You paste the same background again, and a wrong price slips out the day you forget a line.
Do this instead
Make one Project per business or big client: instructions for how to write, the few files ChatGPT should always check, and project-only memory so its chats stay in their own lane.

ChatGPT Projects: Keep Your Brand Voice, Files and Instructions in One Place. Set up a ChatGPT Project with your brand voice instructions, your price list and your style guide, so every new chat already knows your business. You do every step yourself in a practice copy of ChatGPT, it checks your work as you go, and “Do it for me” finishes any step you get stuck on. Free, and nothing touches your real accounts.
