You can put creativity into most things that you do... I think most jobs allow at least some room for new ideas and creativity, as long as there is a fairly high skill roof (which there is in most things).
Academic? Be snazzy in your papers, and intuitive in your research.
Chef? Think up new recipes and different styles of cooking.
In what I'm doing with brain science, I guess it is creative looking at things that may not be very obvious... and look into innovative research, treatments, and ideas etc.
