I'm learning C# and understand the syntax and basic language features, but object-oriented programming still feels confusing. I understand simple ideas like classes, yet I struggle when a project becomes more complicated than a basic console banking program. Should I spend more time practicing OOP before moving on, or start learning other topics and build something larger? I'm getting bored with console exercises and would like to create a desktop, web, or other practical application. Does OOP become clearer naturally through practice, and what would be a good next step?

Try applying OOP to your existing banking project instead of relying only on generic Animal or Car examples. You could have a base Account type with specialized accounts such as ChildAccount, RegularAccount, and SavingsAccount. Shared behavior can live in Account, while each account can customize rules such as withdrawal limits, credit access, or approval notifications. Seeing inheritance and overriding solve an actual problem is usually more useful than memorizing definitions.
Learn the fundamentals, but don’t rush into design patterns yet. Build a small project, let the code become somewhat awkward, and then refactor it. That process teaches you when composition, interfaces, inheritance, or a pattern such as Strategy is actually useful. Patterns are much easier to understand once you have encountered the problem they are meant to solve.
Move forward and start building a small application that genuinely interests you. Some OOP ideas only become clear when you run into problems that need better organization. A desktop or web project will give you more realistic reasons to separate responsibilities, create classes, and improve messy code. You don’t need to master every concept before continuing.
Don’t assume OOP will automatically become clear just because you keep studying it. Even experienced programmers find it difficult because the real challenge is deciding which object should be responsible for each piece of work. For every class, ask what its job is, what data it should own, and what operations it should provide. A simple diagram showing how the objects interact can also make the design easier to understand.
That makes sense. I think realistic rules would help me understand why the different classes and methods are needed instead of just creating classes for the sake of the exercise.
