I'll go first!
This was advice that was given to me directly when I was getting ready to launch my first business as an esthetician.
Utah offers free business support, so I jumped on a call with one of their experts. The ONLY suggestion he gave (which he was very, very proud of) was giving ChatGPT a few prompts so it could write me a full book.
I could then sell that book as a digital download on Amazon and claim I was then a "published author". Apparently, that would skyrocket my credibility, set me apart in my field, and then everyone would book with me.
