Take a look at Emilie Wapnick’s TED talk.
The blurb on the TED site indicates where Wapnick is taking her viewers:
What do you want to be when you grow up? Well, if you’re not sure you want to do just one thing for the rest of your life, you’re not alone. In this illuminating talk, writer and artist Emilie Wapnick describes the kind of people she calls “multipotentialites” — who have a range of interests and jobs over one lifetime. Are you one?
Her message is worth pondering and sharing with students.
