The phrase you provided, "Not all who wander are lost," is a well-known line from J.R.R. Tolkien's poem in The Lord of the Rings. It suggests that wandering or exploring doesn't necessarily mean someone is aimless or without purpose. Many who wander do so intentionally, seeking adventure, knowledge, or new experiences. If you'd like, I can provide more context about the quote, its origin, or its meaning!
