01
Use your own explanation
After reading a small section, close or look away from it and explain the main idea in ordinary language. If you cannot connect the terms, identify the part that needs more reading.
A note does not need to reproduce every detail. It needs enough context for you to understand the idea and find the authoritative source when a precise implementation question arises.
02
Separate fact and interpretation
Mark what the source establishes, what you inferred and what you are still unsure about. This prevents a tentative interpretation from becoming a confident statement simply because it was written down.
Include an example only when it helps expose the definition or trade-off. Label invented details explicitly and avoid using confidential account information as convenient practice material.
03
Leave a next question
Finish with one question that would move the learning forward. It might concern a limitation, a different case or the responsibility of another role.
Review that question before opening another broad collection of articles. The aim is a coherent line of understanding, not a large archive of unread links.
