This quote from Orson Scott Card's "Ender's Game" highlights the theme of mastery through simplification. The character reflects on how, amidst complex situations, the only skill they've honed is the ability to discard unnecessary options. This speaks to the nature of problem-solving where sometimes the best approach is to focus on what doesn't work, thereby narrowing down the possibilities.

Additionally, the mention of the toilet adds a layer of humor and relatability, suggesting that profound insights can emerge in mundane settings. It emphasizes that even in everyday life, moments of clarity can lead to better understanding and decision-making. Overall, the quote encapsulates the duality of simplicity and complexity in navigating challenges.
