Originality really isn't the right word. I've been original my whole life -- almost everyone has by definition. I can do a lot of original dumb stuff. I think what you want is closer to ingenuity. And this is why mastery is important. And its also why mastery of certain things is important. I was one of the most original (and skilled) Gorf players of my day -- no one really cares. Had I been equally skilled at chess I probably could have gotten into Harvard on that alone. Both relatively equally non-transferrable skills.
