#effectiveness #time Efforts will require a fairly big quantity of time to bear fruit. > Most of the tasks of the executive require, for minimum effectiveness, a fairly large quantum of time. To spend in one stretch less than this minimum is sheer waste. One accomplishes nothing and has to begin all over again. > To be effective, every knowledge worker and especially every executive therefore needs to be able to dispose of time in fairly large chunks. To have small drips and drops of time at his disposal will not be sufficient, even if the total is an impressive number of hours.
