It's endless, the missed opportunities. I watched Tamara's Corchevel video and she made a point of talking about the sled pulling dogs, that their purpose is to do that, that they've been bred to do so for hundreds of years, etc. A simple example, but not a rare one. Tamara is curious about the world, and it shows. She is obviously smart as she has qualified as a pharmacist, which is not an easy career. She is obviously well read and takes in far more on her brand trips than just the freebies thrown her way.
Lydia never even gets the fabric content correct on items she is paid to promote. She can't describe fragrances beyond "OH WOW, THIS IS SO AMAZING! IT SMELLS LIKE ME!". Everything is "beautiful", or "bespoke". Or her favorite, "TOO BIG". Her offerings aren't informational at all. Even her "get ready with me" snippets are useless as she doesn't explain the why of what she's doing. So her audience isn't learning anything whatsoever and that's fine if you want a mindless junk food bingewatch. But it goes to show how truly vapid her soul is.
She isn't interested in the world. She has the opportunities to visit incredible places, is given access to pretty amazing things, and has all the time in the world to actually read and learn about anything you can think of. But she can't even pronounce the names of the things she's being paid to promote. And don't get me started on the simple skill of grammar. She literally doesn't give a duck. It's funny to me because I feel there is definitely a segment of the population that judges those with poor grammar, but she's so thick it doesn't matter to her. As long as that Adsense money keeps getting deposited into her accounts, she will continue to glibly swan from room to room of her mausoleum, with a camera in her face, preening and touching her hair, rubbing her face, and scratching her nose, all whilst eye bleeping herself so hard that even the way she walks looks affected.
