The most interesting thing is that even you just read the same lind of proof the next day, your comprehension will be better even if you JUST READ it. You can comprehend it naturally. This is obviously the work of inner mind. But I just feel it takes TOO long for the materials to gel. Besides, if you want to be able to apply the materials, you need to solve problems but even one question can take a LONG time to get you stuck in. However, you can solve it in 15 minutes when you solve it again a week later. In short, if I am given unlimited time, I can do whatever I want. BUT it just takes TOO long.
I have read through all the posts of KW. Obviously economics has a lot to do with maths BUT econ maths are not like Maths. Maths are more rigorous and Maths have no numbers and are purely algebra. He told me that he superread and dipped the proofs several times. I tried but could not make it. I even tried to regular read it for several times, the effect may be better but it is not good enough. Besides, KW can carry on to superread and dip the latter part of the book even he doesn't know the previous part. For me, I can't understand the latter part without knowing the previous part. This is the main problem. Maybe KW's method applies to essay writing most effectively.
Lastly, I think KW has also learnt a lot of courses like silva method to boost his body mind connection. I don't know which courses would be great to improve this area.
