It really won't matter to you what I prefer! People ask others' opinion but mostly end up following what they are comfy with! Just wait till you're a grown up! I'm sure you'll know what to become! Don't worry, I've tried it!
I don´t know what i want to do in the future!! Doctor, lawyer, singer or interior designer???? Which 1 do you prefer??
I prefer doctor, dentist is even better.
You must have a choice, choose the one that you are interested, and easier to earn money as well, as some kind of jobs are difficult to obtain, but the main is you should have your decision. And good luck.
