   It seems that fiction is much easier to remember than non-fiction. Fiction is more visual and easy to grasp. I can recall a plot of a lot of fiction books I've read. As I said I can't do that for non-fiction. The reason for that I think lies in the nature of non-fiction books. Non-fiction books are about ideas. Ideas are abstract concepts. They are not always directly tied to reality. In order to remember such book later, you need to understand it very well. In order to understand non-fiction book you've need to build mental model of this book in your head. Non-fiction authors have a mental model of the world in their heads when they write a book.Your goal is to rebuild that model in your head, to make it physical. Non-fiction sounds a little bit like programming. The code is an abstract expression of author ideas about the world. Your goal is to grasp it now and make it possible to recall in the future.
   
  -Thinking of this difference between fiction and non-fiction I realized that Alain de Botton's The Course of Love written in a most brilliant way. It's written like a novel (fiction) but it has quotes of his main ideas in each chapter (non-fictional ideas in a non-fictional style). Those quotes are important there because sometimes it's not always easy for you to formulate idea nicely even after reading the story. I wonder if there are other books like that? That is an interesting approach for modern journalists, philosophers to take: pick your serious topic and present it in a fictional way but express and highlight your main ideas directly.

  -Another good idea is to read books in pairs. I mentioned before Brave New World and Amusing Ourselves to Death. These two books work great together. It's much more difficult to extract true value of Brave New World by yourself. E.x. for me world described by Huxley was scaring but I couldn't formulate all the reasons why it was that way. Postman gives you good explanations why. He gives also real examples from moderns times that you can grasp more easily.

   So it seems that there are possible solutions to the problem of forgetting. It seems that sometimes we can make a process of remembering easier. But I don't think that this is the main takeaway. I think the best thing we can do is to invest more time and effort into reading.

  I've read several books that I was super excited after finishing. Books like Sapiens, Bruce Lee Striking Thoughts, Bertrand Russell's Best, Ill Fares the Land and few others impressed me a lot, they presented some new ideas I didn't know, some wisdom, approaches etc. They triggered a lot of thought. I was very enthusiastic after each of them but the problem is few month later I couldn't remember a single idea of any of those books. I don't know what I liked about "Sapiens" book, I don't remember what Bruce Lee's insight I liked. The only thing I remember is whether I liked the book or not. I remember my feelings about the book, not the ideas presented in it.
  
  I recently finished reading two books that go well together: Brave New World by Aldous Huxley and Amusing Ourselves to Death by Neil Postman. This is truly the most powerful pair of books I've read in years. After finishing those two books I've got scared that in 3 months I would forget what I liked about them and what were the ideas of those books. And I don't want to forget. Those books contain ideas of high importance. The same is true about books I enumerated above.
  
  So what should I do?
  
  
negative.code:  - find a book club where you can discuss your book and discuss it with people. Giving 1 min summary of a book for people who never read it might be very useful for you
  
  Theoretically, there can be also the technological solution for this problem. 
  It might be something like an online non-traditional book club that would be similar to a school classroom I described above. 
  You will become part of the classroom with other people who are reading the same book right now and willing to join. The classroom would include several discussion sessions and writing essays and tests.
  
  However, I'm not super optimistic about such technological solution at this point of time. 
  There are a lot of open questions. 
  Is learning more social or individual activity (does the answer depend on a type of personality)? 
  Is it better to have a solution that satisfies fewer requirements but offline (think book club) or online one that is theoretically more feature-complete?
  
  So I'm sticking with my experimental ideas presented above. 
  At the end, I would definitely read fewer books but hopefully, I would understand and remember each of them better.
