The document discusses knowledge workers as defined by Peter Drucker in 1959 as those who primarily work with information and develop knowledge. It says that to be a knowledge worker requires having a broad set of skills, using a wide range of tools, freely sharing information, being creative, innovative, intellectually present, and always seeking new knowledge. It advises that to become a knowledge worker one must keep learning, obtain sources of information and put them into practice. The reasons given for wanting to become a knowledge worker are that the world is constantly changing, it makes one a more valuable resource, and knowledge is power, rather than becoming obsolete.
