I'm in the same boat, but not self-taught. I used to knew OOP. It was so obvious, you just made classes of things with methods to do actions. Then the things could be inherited from to create sub-category objects to be acted upon. Then I read some articles. And I read forum posts. And I read comments. And I read OOP doesn't need this or that. I read multiple people define OOP in many different ways. Now I don't know how to define OOP. I thought I could "know OOP if I saw it". And then I wrote code. I wrote in procedural languages. I wrote in functional languages. I wrote in declarative languages. I wrote in languages that like to blur the lines between them. And now I don't really know where the lines are. It all is just "programming". Answering the question: "What is Object-Oriented Programming" used to be so easy. Now I don't know.
