I don t know how other people do it, but i hate it. That is why i created this thread for me( perhaps people like me). I want to know your way to approach a book. do you like to question every sentence. do you try patiently to wait out every problem. do you try to work on the problem before working on the concepts? understand something means able to clearfy that something in your mind that goes not longer than a couple of sentences. It is to me the ultimate data compression algorithem. This sort of reminded me of how zen master do their mediation, or how chess master play cless. That is why i am interested in how people learn.
