Quote by Sir Arthur Conan Doyle
A man should keep his little brain attic stocked with all the furniture that he is likely to use, and the rest he can put away in the lumber room of his library, where he can get it if he wants it.
Summary
This quote emphasizes the importance of being selective in acquiring knowledge. The "little brain attic" represents one's mind, which should be equipped with the information that is frequently useful or applicable. This implies the value of keeping the mind organized and prepared with the necessary knowledge. On the other hand, the "lumber room of his library" suggests that less relevant or lower-priority information can be stored away but still accessible if needed. The quote encourages a practical and organized approach to managing one's knowledge and intellectual resources.
