not everything that is learned is contained in books...

I think book is important because you would know many things from the book but experience is something that not everybody could get. From the book you would be able to learn other people's experience so by reading the book you can compare your own experience and the other people's experience so you would learn many things from them. From people whose life is lack of experience they only able to learn from the book. They only know the theory but never know how to really apply the theory in reality. But those who only learn from the experience would never know that there is something else then what they know outside their own little world. I think both of them is important.
