text: after years of effort you come to realise that what you learnt so far is wrong.what do you do ? how does the process of unlearning and relearning work ? we have to change our understandings of the world around us and our knowledge base throughout our lives as the world and society change and our understanding of them change.  when we start a new job or leave high school for university or get married we have to leave behind some of our old ways and learn new ones.    actually, "unlearning" can be harder than "learning".  it is rather like breaking a habit - can be very difficult to do.  it is why once a baby learns that mom or dad will come into his room if he cries when he is put to bed, it takes quite a bit of persistence to break that cycle.  you have to focus on the "unlearning", depending on what the topic is (this would bve easier to answer if we knew what you have to "unlearn").  and persistently practice whatever the new behavior or idea or concept needs to be.  these links may help.
