Why you DON'T want to be a model Sure, you can think of a hundred reasons to be a model: the glamour, the fame, the money, the freebies. But are those things real? Be sure before you take the plunge.
Many models spend hours learning tricks, and getting the spot can be tricky. There are prejudices in some places against people of certain colors, sizes and proportions (though that is changing these days), and the competition is more than fierce. Most models have to adhere to regimented diets to keep their weight, need to watch their outer appearance all the time, and still keep their inner selves healthy and content so that they can live their lives happily.
Aside from that, there is the issue of money. Models usually get paid by the hour or by the jobs they do. If you're used to a steady salary, it's not an easy switch. Until you become a superstar model, be prepared for small paychecks and a tight budget.
If you do happen to make it big, it doesn't get easier. This is not a job for the faint of heart - long hours, constant public scrutiny, rigorous discipline with your body and habits.
Finally, the job of the model can, indeed, be glamourous, but consider the risks - if you don't make it, are you willing to keep trying? Will you give up many things that you don't consider luxuries in your life? Can you travel and move and face family tension? These are all issues to be faced in the world of full-time modeling.
Ultimately, you should do it because you love the job, not for the fame or the glamour the career brings. It's the enjoyment of the professional career that makes stars of models, and the confidence and persistence they exude (not just their beauty) that makes them famous.
