OOP is a way of looking at a problem and map it into code. Some problems will fit into it, some don't. Some people can look at problems and see objects and some can't. But in most cases, it is not easy to take an existing procedural program and re-map it into objects. It would be easier to start over from the specification and write it from scratch in the object model. If you have been doing procedural programming, don't worry if you don't figure it out right away. It is not an easy transition to make. Many of us with decades of programming behind us will never be able to make that switch. Our brains are too tightly locked into the previous thought patterns.
