Break things down. I'd start by getting an overview of the problem - in this case it's probably chapter names in a book. Then for each module, break down what you'd like to learn further into sections that take < 2 hours to complete thoroughly. After each 2 hour module, write down your key takeaways of the trickiest part you learn and pause. Then, when you're ready, resume for the next intense chunk. You can re-read your highlights at the end of the day to help absorb more deeply. I've also found the Cornell Notetaking method (http://lsc.cornell.edu/study-skills/cornell-note-taking-system/ http://lsc.cornell.edu/study-skills/cornell-note-taking-syst...) to be a helpful guide. It includes the "summarizing" step and a recommended structure for organizing notes both as you're reading/watching and when you're solidifying this knowledge.
