In "The Glass Castle," Jeannette Walls reflects on her unconventional upbringing and the lessons she learned outside of traditional education. She emphasizes the idea that knowledge and understanding of the world can come from life experiences rather than formal schooling. This perspective suggests that being observant and engaged can lead to valuable insights that are often overlooked in a classroom setting.

Walls' statement highlights the importance of self-directed learning. It underscores the belief that one doesn't necessarily need a college degree to grasp significant truths about life. By being curious and attentive, individuals can educate themselves and become aware of the realities that shape their existence, a theme that resonates throughout her memoir.
