My method to learn most things (mostly applies to technical subjects learned as a hobbyist in my case): 1. Grab all the textbooks I can find on Libgen on the topic. 2. Read tables of contents to get a high level view of the main components of the subject and the scope of what you want to learn. 3. Start reading (I usually skip introductions too) from the textbook that looks most appealing/authoritative (cross check on Amazon, or curricula from well known universities, but sometimes even the design of the textbook can make it more motivating/easy to consume, e.g. I hate most "modern" textbooks that have 25 random boxes of text per page — very confusing reading experience). 4. Keep going until you get confused/tired. 5. If still motivated/have enough energy, see how other books cover the same topic to see if it's clearer. 6. If you're too tired to read, try Youtube videos covering the topic. 7. Sleep. 8. Repeat, start over from where you feel you have good command of the topic.
