I think the ceiling is less about what you can achieve, but about the quality you produce (e.g. correct application of principles, which can lead to better maintainability). Before I studied I thought of objects in terms of Object Orientation as a memory layout plus some functions to manipulate it. When I studied, I learned that Object Orientation is much less about the implementation, but more about the principles at hand (e.g. polymorphism). I still love good implementations, but studying gave me a whole new perspective on certain topics.
