A system to help you remember more of what you read
I find that simply sitting and thinking while -- and after -- reading nonfiction (or fiction, if it's got good ideas) burns the facts and ideas in as well as anything. I don't think most people allow as much time for reflection and mind-wandering as they ought to; expecting yourself to remember fact after fact without taking time to really absorb, reflect, and expand on them doesn't seem realistic.It's not unlike a memory palace -- rather than just read the fact, think on it, expand on it and give it context and a place to live in your brain.
