When you're at that point, it's usually a sign that you need to start applying what you learned. There are two parts of programming:

1. The concepts, the theory which is honestly the fun part.
2. Dealing with the little annoyances, setting up a development environment, learning APIs, wiring things together, running into problems there is no clean solution for and implementing something that works.

The second part feels unimportant, something you can always learn later, but it takes time to learn and get good at, and what you need to learn to start to effectively apply more advanced concepts. Otherwise you're learning things you won't be able to use.
