The most important contribution management needs to make in the 21st century is ... to increase the productivity of knowledge work and the knowledge worker
Our job in life is to make a positive difference, not prove we're right.
Profit is not a cause but a result-
There are no creeds in mathematics.
We always remember best the irrelevant.
To be effective, every knowledge worker, and especially every executive, therefore needs to dispose of time in fairly large chunks. To have small dribs and drabs of time at his disposal will not be sufficient even if the total is an impressive number of hours.
