GPTs are incredibly useful. They can save you a lot of time when drafting and prompting. 

That said, treat them as a helpful assistant, not a miracle worker. 

After the first draft, it’s normal to want revisions — simply describe the edits you need.

For personal use...

And if you want to sell it or give it away to your audience...

P.S. For best results, it's preferable to be logged-in a paid ChatGPT account. I never tested it on a free account.
