Am i starting late..?

i feel like i'm late. i'm 14 years old and every other kid i know already knows what they want to be when they grow up. i, on the other hand, can't even think about that. i have so many interests, it's hard to only consider one for my future profession.. at school, my teachers were handing out these little booklets and it said that by your freshman year, you should have a good idea of what you want to be. is it okay that i'm not quite sure yet or am i late?
