I honestly think that she truly believes she’s a guru of some sort. I think she thinks that the “influencer” route is beneath her. The fact that she sold a course for 1K and many people bought it (I’m guessing at least 50 people bought it).. I’m sure this went to her head big time, inflating her ego beyond any type of “success” she’s ever experienced before. What other success has she had? I haven’t heard her brag about anything academic, educational, sports related, family related or even crafts/ hobbies related.. and she’s in her mid thirties!!
I guess we could say that her “talent” is stealing info from books and other sources and rebranding it as her own (as you mentioned). People that aren’t used to doing their own research will continue to buy her course because they don’t know any better. BUT I can bet that once those customers buy her course.. they will probably feel like something was missing and more than likely realize that the only info she’s “good” at providing is quite shallow.
