Not Everything That Is Learned Is Contained In Books.
Our first knowledge we get from school by using the books. Since we know to read, book going to be an important sours of knowledge in our life. In the early age, all information is important and has a big value, but by growing up, we start ask questions the answers to which become difficult to find in the books.
One of the questions is can I trust to someone who I know or I only think that I know him? I can read tow thousand philosophic and psychologic books but not in one of them I do not found answer to my question, until I would get my own experience with this specific person, I could not know can I trust him or not.
Another example is the physical experience that I could get only by training. There are a lot of books had written about sport exercisers and even if I had ability to read all of them I would not be stronger, faster or flexibilier only because I know how to do it. Only after hard workout in the gym, of cause with right knowledge about all the process , I can get to my gain like to do salto in acrobatic, or to run faster in atlethik, or to do strong hook in boxing.
Actually, I can collect my own life experience without knowledge has written in books, but it probably will not be so correctly way to learn thinks. I think it is very important to collect book- knowledge and to combine it with really life experience to getting by perfect way to some specific aim.
