“There was no point in constructing a schedule we could not live with.  There was no point in creating a schedule for someone whose work attitudes were conflict-free, because we, the people for whom the schedule was intended, were not conflict-free.  We might wish, for example, that we were people who never wasted time, but we were people who did sometimes waste time, so we explicitly designed our schedules with that in mind. . . . Most time-management formulas presuppose that the problem is managing time, [and] that problem has fairly mechanical solutions.  The real problem is figuring out what one can and will do.”
