I wouldn't say that I love her, but I do like her philosophy. I guess her style of interaction could be described as "cutesy" or "too sweet." Some people like that sort of personality but I tend to be suspicious of it
I read her book about a year ago, before her show was even a thing, and I do like the idea of getting rid of things that don't spark joy. My own house is far too cluttered. I'm not a hoarder; people can still easily walk through my home and I don't keep multiples of anything except my fish tanks and Pusheen plushies. Both of those collections do spark joy for me so I don't know that she would tell me to get rid of them, either. But I do dream of one day putting her system into place and getting rid of all the things that I don't need or enjoy.
