If you don't know where you are going any road can take you there.
This quote belongs to the Cheshire Cat, a character from “Alice in Wonderland” by Lewis Carroll. He says it in Chapter 6 during the intriguing conversation with Alice. Alice is exhausted after all the size changes and illogical things happening around and asks the Cat for a piece of advice. The Cat soothes her, in its own manner, though, saying that they are all mad there and, perhaps, Alice is too. This quote (it’s a bit longer in the actual dialog from the book) is the answer to Alice’s question about the direction she should go. Alice doesn’t know where she wants to be and what she wants to get in the end, so Cheshire Cat supposes that any road will do to reach at least something (if she walks far enough!).
