Quote by Samuel Butler
Everyone should keep a mental wastepaper basket, and the older he grows, the more things will he promptly consign to it.
Summary
This quote suggests that it is important for individuals to develop a mental wastepaper basket where they can discard unnecessary things as they age. With time, one's ability to recognize what is truly valuable and significant is expected to mature. This mental wastepaper basket functions as a metaphor for the process of intellectual and emotional filtering, encouraging individuals to let go of trivial matters and focus on what truly matters in life. Therefore, the older one gets, the more proficient they become at discerning what to disregard and what to cherish.
