I dont know what I want to be when I grow up?

Singing shouldn't be a high priority because of its dependability. Lets face it, not very many people can be successful singers. If you have a fear of needles, i wouldn't suggest being a dentist. Not only because of that fear, but because you didn't mention having a pion for learning about the human body and bacteria. Pastry chefs can make a lot of money and be successful, and it seems liek you have a pion for this. Good luck in following your calling. I am 17 and plan to go to medical school to become a specialist, possibly in plastic surgery or something of that nature. I am taking cles like anatomy and chemistry now to help give me a pre background in this. I suggest you do the same like taking culinary, business management, etc.
