Others have said something similar, but I will still chime in. It sounds like you may want to feel like you have a complete understanding of classes, objects, and the way the work before you can begin working with them. This can almost never work. I haven't come across a topic where just reading about the topic is sufficient to fully understand it or even become proficient in it. In my experience this is true for cooking, lab techniques in chemistry, electronics, and programming. Even when I have read something and felt that I understood it completely, as soon as I begin the activity I immediately realize that I had a fundamental misunderstanding of what I had read. That my brain had made some oversimplification or skipped passed some details so that I felt like I grasped the concept. So if I had to describe the way I learn a new concept it would look like this: 1. Read many different descriptions/watch many different videos of the topic to get used to the terms and concepts 2. Try to apply those concepts in real life (write software, build a circuit, cook a meal) 3. Figure out where my understanding fell short, and go back to step 1 You want to make this loop as tight as possible. When you become expert at something you can do this activity super fast. When you first start out you may have to do quite a bit of reading to even have the baseline needed to attempt a concrete task. However, it is important to get started towards a real goal as soon as possible or you will be wasting your time feeling like you are learning and moving towards you goal, but you are not.
