I always ask people who design to watch Scott Berkun (ex Microsoft IE lead but don't hold that against him) talk about the Myth of innovation. I have met too many designers feeling like they haven't had "the lightbulb" moment and he talks about how it doesn't exist. Experience and years of insight lead to innovation. https://www.youtube.com/watch?v=amt3ag2BaKc

I also reference this one a lot about basically why certain people lead the way (in design and other areas) while others stumble. http://www.ted.com/talks/simon_sinek_how_great_leaders_inspire_action.html
