I am more interested in polymer materials and engineering. I am a girl and I am now in the third year of high school. Is it worth learning?

I have seen a lot of saying that this major is not good for health and the salary is not high, but I am more interested in it, and I can also go to the current top professional school. I want to see if there are any seniors who study this major for advice.
