I was fascinated by several observations Gladwell made about the genius of Steve Jobs, late Apple honcho.
About him being an Editor, not a writer. About him refining the creations of others (as if a half a hundred hadn't thought of a tablet computer before?). About him throwing a fit because one of his creative staff wanted more direction and less...editorializing.
There is much to ponder in here about the proper role of the PI that you work for, are, hate and/or want to become.
