Calvin Coolidge on Delegation

"In the discharge of the duties of the office (of the presidency) there is one rule of action more important than all others. It consists in never doing anything that some else can do for you. Like many other good rules it is proven by its exceptions. But it indicates a course that should be very strictly followed in order to prevent being so entirely devoted to trifling details that there will be little opportunity to give the necessary consideration to policies of larger importance."
