People gain knowledge from life and books. II On the other hand, workers, farmers, scientist and other groups of people gain knowledge from experience. For instance, workers develop skills through years and gain knowledge in areas such as driving, operating and maintenance, for example. Furthermore, farmers gain knowledge after growing plants. They will improve their abilities about the process and techniques of plantation. Next, scientists gain knowledge after finishing an experiment, for example. Summing up, some people gain knowledge after planning and executing a project or activity. In summary, books and experience are abundant source of knowledge. However, if we put both of them in a balance to identify which one is better; it would be a difficult task. It is because everyone has different way to gain knowledge. While some people gain knowledge from books and experience other people, who never went to school, gain knowledge from experience.
