The best way to learn is to teach. One of the best ways to teach is to follow the Feynman Technique of learning.

I am reducing this teaching and learning method using the 1-2-3 Creative technique so it would become:

1. Explain the concept you want to learn using simple language as you were teaching it to someone else. 
2. Identify unclear areas. If needed, review the original sources. 
3. Simplify all difficult parts of the concepts.

You could facilitate your journey through the three steps by asking questions.
