What to be?

I go ATC and really enjoy everything bout it and would love to go in to the RAF when im old enough but then I also want to be a singer...? I so confussed why are these two career paths so different?

I think you should follow with what you are doing now and maybe do singing on the side. Because you could have a great career and do singing in your spare time and go somewhere with it as well. I don't recommend you dropping your career path right now for a singing career because its such a difficult industry and isn't very promising.
