“You cannot achieve everything, certainly not at the same time. There are only so many hours in the day, only so many issues that any person can be expert on, only so much access that you can enjoy, only so many decisions that an organization can make. Priorities matter; sequence, too, can be terribly important. The key is to focus – something that takes real discipline, since in a typical day you might be confronted with more than a dozen issues, as many phone calls, several meetings, and inches of paper to read.”

(from Richard N. Haas, The Bureaucratic Entrepreneur. How to be effective in any unruly organizations, Brookings Institution Press, 1999)
