Everybody is entitled to their own opinions — however, I do think you wrote this article to bash Rachel and her success. Every good writer has in some shape or form plagiarized another's work — not intentionally, of course. However, think about how much you read. Think about how much TV you watch. Think about how many podcasts you listen to. Reading is how you feed your mind if you end up repeating an idea someone once said because it’s what is engraved in your brain, perhaps that's just what stuck out to you. Perhaps that is just what you are or have been applying to yourself.
I’m in no shape or form trying to bash what you wrote, I think it’s a great and interesting read, but I don’t think there’s any reason to paint her so negatively.
