Career Help, please.

Hi, I'm a girl and I'm 12 years old. I don't know what I want to be when I grow up. All of my friends do, so does my brother and my sister. My dad wants me to choose a certain career path but I don't know if that's what I want. He has expectations that I'm supposed to live up to. I'm just so confused about what I should choose. Can you suggest anyways to help me find out what I want to be in the future? It would be greatly appreciated. Thanks in advance.
