Im 13 and want to be a glamour model but is it a good career or not and is it hard to become one?

Some models do extremely well and become wealthy and famous, however, you have to be just amazingly beautiful in order to be that successful. There are, let us remember, about seven billion people in the world, which creates a lot of competition. Even if only one person out of ten thousand is exquisitely beautiful, that still comes to about seven hundred thousand exquisitely beautiful people in the world, and the demand for fashion models is not nearly that high (there may be a thousand people in the world who make their living as models). So, how beautiful are you?
