"Oh, The Places You'll Go" by Dr Seuss

Plot from wikipedia

"The story begins with the narrator, relating the decision of the unnamed protagonist (who represents the reader) to leave town. The protagonist travels through several geometrical and polychromatic landscapes and places, eventually encountering a place simply called "The Waiting Place", which is ominously addressed as being a place where everyone is always waiting for something to happen. As the protagonist continues to explore, spurred on by the thoughts of places he will visit and things he will discover, the book cheerfully concludes with an open end."

Hexaflex points addressed

Self-As-Context - At one point the narrator talks about how difficult some of the challenges you will faces will be. "Games you can't win, Cause you'll play against you."

Commited Action - The narrator tells the reader about getting in a slump he states "Unslumping yourself is not easily done." But the point is to keep moving forward

Experiential Avoidance - The Waiting Place is where people are waiting for things to happen to them instead making things happen. It doesn't say exactly why, but I think it's fair to say that they are waiting to avoid being uncomfortable. This reminds me of the Waiting for the Wrong Train metaphor.
