All tutorials, books and courses will only teach you the basics. If you really want to know blueprints:
- you must set goals and then find out how to achieve them;
- explore and experiment.
For example, you came across the DoN node. Now, you must use your imagination and think: “what can I do with this? where can I use this?”. And then try it out.
My view is: All the learning material out there, do not exist to teach you how to do things. You should consider them as showcases: they are only there to show you a few features and aplications.
