This is the "curse" of the hot chick: it's virtually IMPOSSIBLE to get honest feedback from the world. Meg's not even funny for a group of friends--let alone as an actual professional comedian. From what I've seen, this hot chick curse comes in two forms. In Meg's case the girl actually BELIEVES all the positive feedback she gets on her subjective "skills" (like comedy) even when she's at best truly mediocre. That can lead to what we're seeing here--time and energy wasted on a pursuit that she doesn't have the talent or the work ethic to make work. The flip side of this curse I observed with a now ex-girlfriend. She actually WAS pretty smart and talented, but for a LONG time she had zero confidence in her abilities because she was always suspicious that she was being praised for her hotness. Again--impossible for her to get honest feedback from the world. It's a pretty weird problem to have when you really thinking about it!
Megan's actually managed to cultivate the perfect audience for herself. A weird, nerdy chick with big tits who played on that fact and kept them hidden long enough to create an army of simps who'd be happy to finance her life in return for a handbra pic a month. She doesn't even need to do anything or show more than she already has. Much hotter chicks than her are desperately posting full frontal nudes hoping for a fraction of that attention and nobody even knows they exist.
