In Alice in Wonderland, Alice asks the Cheshire Cat which road to take. His response is "Where do you want to go?"
Alice says, "I don't know." Then the cat says, "It doesn't matter." Explain.
If you don't know where you want to go, if you don't have goals, then it is difficult to determine which way you should go in life. By having goals, you can chart a path to where you want to go.
