Well . . . no. Not always. Imagine you could see the whole of the web, billions of pages, stretched out in front of you, and you’ve got a question you want answered. You know that the answer is out there in that immense array of pages. But how are you going to get to it? You could jump in and flounder around – but you would do a lot better if you spent a few seconds thinking about asking the right question.
