If you want to learn facts, then you should use a spaced-repetition system (SRS). You break knowledge you want to acquire into short answers to tiny questions, and then you make digital flashcards of those in an SRS program, which will then prompt you to review them at the most efficient time for strengthening your memories: right before you were in danger of forgetting them. You learn fast, you remember almost everything, and it’s easy to turn into a daily habit that can deliver massive piles of knowledge in a few minutes a day.
