In "Half Broke Horses," Jeannette Walls emphasizes the idea that everything in life serves a specific purpose. This perspective suggests that every action, object, or choice has a reason for existence, and if it fails to fulfill that reason, it is essentially pointless. This philosophy challenges people to evaluate their lives, encouraging them to focus on activities and possessions that contribute positively to their experiences and the broader community.

The quote reflects a practical approach to life where efficiency and meaning are paramount. It implies that simply existing without purpose is a disservice, not only to oneself but also to others. Walls invites readers to consider what truly matters and to eliminate distractions or inefficiencies that do not serve their goals or aspirations.
