Tell me about a job that you want to do but may never have a

In my dreams,I want to be a actress of a film,then I can fly,I own kung fu,and maybe I also can a beautiful policewoman,because actress can act different people,and we can know different people from the person I act,so I want to be a actrss very much.But I donot want to do it for all my life,only have a chance to play a film,it1s enough to me.I donot know if I will have a chance in the future,but I will try.
