“Every top executive and every analyst sitting at the center of a communications network should periodically emerge from his world of abstractions and take a long unflinching look at unprocessed reality. Every general should spend some time at the front lines; every research administrator should spend some time in the laboratory doing research of his own; every sales manager should take his sample case out periodically and call on customers; every politician should get out and ring doorbells.”

John W. Gardner, Self-Renewal (Page 79)
