PG wrote in one of his essays that he used to sleep in the morning, doing stuff involving others (like meetings) in the afternoon and coding in the evening and night to avoid interruption. Ben Horowitz wrote in his book that the most productive management style is to assign one task only to one person and allow him to make decisions on his own without to force him to discuss everything with a bunch of people. IMHO the key to productivity is managing your tasks/team in a way avoiding interruptions and reducing communication to the minimum.
