Over the next 70 years, Drucker's writings would be marked by a focus on relationships among human beings, as opposed to the crunching of numbers. His books were filled with lessons on how organizations can bring out the best in people, and how workers can find a sense of community and dignity in a modern society organized around large institutions. As a business consultant, Drucker disliked the term "guru", though it was often applied to him; "I have been saying for many years," Drucker once remarked, "that we are using the word 'guru' only because 'charlatan' is too long to fit into a headline."
