I really enjoyed this piece by Shawn Blanc:

But what is important is remembering foundational principles for how to live life and to live it well. Our values, ideals, thoughts, emotions, and habits are bombarded every day by the media. Movies, commercials, TV shows, and so much more tell us how we ought to live and what we should believe. Which is why our Core Curriculum notebook should be comprised of things that speak truth to who we are, who we want to be, and what we want to do.
