I don't know what i want to be

So basically, I don't know what I wanna be in the future. And I know it's time for me to start thinking. I've thought about it, but I really have no idea.
Nothing really interests me.. and I justt simply don't know.
Has this happened to anyonee? Like...

how did you figure out what you wanna be?

things like this happen all the time to many different people of all ages.. if you dont know what your interests are than go by what you watch on tv... for instance I like criminal shows like csi and ncis things like that, determing the show you like may also help you decide what you want to be.. if you like shows like gossip girl or one tree hill or the hills than you would like fashion if you like politics you could be a person who is an activist if you like make up and hair be a cosmopoligest if you like helping the sick be a doctor or working with kids be a pediatrician or own a day care or a teacher.. think about things like that to help you it helped me a lot
