Sounds like an exam question!
I suppose I would ask first What does 'secret' mean? Is there a secret? What might it be?
Innovation refers to something "new" but "newness" does not necessarily have to refer to a totally new product, it could also refer to new ways of using it.
Sometimes it is helpful to be young and not to know that something "cannot" be done and to have the energy to pursue a new invention. But it's also useful to have the experience to be able to say "I could use this in a different way".
