Hashem implanted in every human being a liking to a particular profession, otherwise everyone would occupy themselves in the same field with no benefit to mankind. You realistically have to take stock in which field is best for you. While a personal shopper might sound glamorous to you at this stage of your life, it might be a dream and nothing more. in the meantime, be a teenager and enjoy life!
My husband since his mid teens knew what he wanted to do as an occupation. He self taught himself his profession while in Bais Medrash, was able to do it in the early morning and at night when he was in Kollel for 10 years and B”H he never looked back.
