Tangential, but I think that one of the greatest gifts of experience and age (not that I'm old, I'm 33 - just not a kid anymore) is a lot of exposure to things I know nothing about. I now know just enough to be able to google lots of different things well, and better, have learned how to discover more things I know nothing about. It's a skill we (humanity) should spend more time developing in youngsters - being a specialist is useful and great, but being a specialist who knows of other specialties is even better, because then it becomes easier to link knowledge sets into awesome solutions.
