The cartoon given above tells us that there are two persons who are arguing with each other about the importance of book Knowledge and experience. In fact, knowledge can be acquired from many sources. These include reading books, classroom activities and practice.

　　The knowledge we gain from books and formal education enables us to learn about things that we have no opportunity to experience in our daily life. First of all, we can study all the places in the world and learn from people we will never meet in our lifetime, just by reading about them in books. Second, we can also develop our analytical skills and learn how to view and interpret the world around us in different ways. Last but not least, we can shuttle between the past and the future by reading books. In this way, we won't repeat the mistakes of others.

　　Practice, on the other hand, offers us more useful knowledge. In fact, as we all know failure is the mother of success. Moreover, if one wants to make new advances, it is necessary to act. Finally, one can apply the skills and insights gained through the study of books to practical experience, making an already meaningful experience more meaningful.
