The boob job was definitely her biggest mistake. The second was her taking too long and too many of unannounced breaks. The third was when she makes content, she undeniably puts in a lot of work, but in the wrong areas, like doing way too many photo sets over videos and doing things like story telling videos, which aren't necessarily bad, but are clearly time consuming to create and energy could have been better utilized elsewhere. The fourth was using her phone camera for making content, instead of a professional video camera and photography camera.
There's definitely still a lot of great potential content to come from her and a lot of things we still haven't seen. It might be a good idea for her to open up a suggestion box for her fans, to help her with some new ideas along the way (just as long as none of them suggest her to get anymore regretful surgeries).
