You are taking a sort of a bottom up approach of learning the languages. It's sort of similar to learning Japanese for the sake of it (which is fine). Language is for communication and of course programming languages are to make things with them. You'll find the process more enjoyable and easier to learn if you learn it with the goal of doing something with it, not just being good at it in general. If you need to make something and you can identify what you need to do to get there, you can start chipping away at the requirements and get closer to your goal, making the whole journey more exciting. Ideally you would approach this from both ends. On one end you are learning bottom up. On the other end you see what you need to make and you backtrack from there until something you know and you try to make your way up.
