Wonderfully insightful about how story works.

The protagonist is often hesitant to start the transformation. “Change is good. You go first.”

This reluctance at the beginning hooks the audience into the story. When it appears at the end of act 2 (the moment of despair / doubt before the rebirth) it energizes the audience after a long and episodic act, as well as creating suspense. (One of the audience’s biggest fears is that the movie will end prematurely.)
