Earlier quoted context omitted.
Right, so like modelling, which is not exactly an obscure occupation. That she did it using instagram doesn't make much difference there. I think it's important to point out that I am an old man, not a teenager, so overdramatizing things doesn't boost my engagement.
Modeling is not an obsession, it's a job. You do it when you're young, smoke a lot of cigarettes etc, and then you move on. It's like grad school but with even more skeezy old guys. (Now, math modeling may become an obsession...) edit: just to be clear, oldmanjay, I am not making any comments about old guys in general! some of my best friends are old guys!
Becoming a model is an obsession for some young women. For models, it's a gig job, and getting gigs is hard. Only the top 100 or so models worldwide make real money. If you're in LA, you probably know some actress/model/waitress types. I had a friend whose career peak, after years of work, was one McDonalds' commercial that got nationwide distribution.
Below the top tier, the work is not that great. There's trade show work as a booth babe. There's catalog modeling ("OK, the next one is the blue sweater, #6522, and hurry it up, we have 20 more to do before lunch").
