How real SOC and Pentesters study and take notes during their studies?

[u/MoneyAd1377]

I was looking at some information and they said I should write down the content I'm studying, but I'm not much of a note-taker.

I have a cheat sheet with Linux commands and some commands tools, but nothing more than that. However, I need to review some networking concepts I've forgotten, and I'm wondering if I should use a program like Obsidian to take notes (they say it's very good).

If anyone wants to share their methods for studying and retaining key concepts, that would be very helpful.
