The best investment they can make is in themselves and to think of life beyond modelling. Because unless you're Kate Moss or Naomi Campbell (and even they've dealt with rich men), there's just no way modelling will carry you until you're 60 uninterrupted. Hate to admit this because I'm not a fan of her at all, but Julia Nobis is on the right track with her priorities. Get the money, and get out. And also, her plan is entirely self-reliant (not sure if her parents pay for her studies, but she can afford it on her own if push comes to shove.) There's no tech exec or Malaysian blood money funding her lifestyle or ventures. So for a model like Erin to go bankrupt, and commercial models earn more than HF, there must've been some gross mismanagement of money.
