Couldn't disagree with this more strongly. You can have a goal. It's good to think about them. But some of the most innovative theorizing in history was done by people with no thought about the practical goal in mind. Studying something simply because it's interesting to you is a valid choice. But you do need to be aware that that's what you're doing, and not expect some reward to materialize other than the knowledge itself. "Why Greatness Cannot Be Planned" is a very good book on this topic.
