What action does Twilly tell Waxmo to take regarding his teaching?

Twilly's instruction for Waxmo to stop teaching for Starch permanently indicates a significant concern regarding Waxmo's current teaching situation. This choice highlights a pivotal moment in the narrative where it is essential for Waxmo to reassess his role and the impacts his teaching may have on his own life or potentially on those he teaches. The recommendation to cease teaching suggests that there may be underlying issues that require Waxmo's attention, which could involve personal development, focus on other responsibilities, or addressing shortcomings in teaching effectiveness.

By advising Waxmo to stop teaching for Starch, Twilly is emphasizing the importance of prioritizing what is best for both Waxmo and the educational environment. This guidance reflects a desire for Waxmo to reconsider his commitments and perhaps to engage in a more constructive path moving forward, rather than just persisting in a role that may not serve his or the students' interests well. This decision underscores the theme of making critical choices in education and personal growth, which are central to Waxmo's journey.
