You yourself are the teacher, and the pupil, you're the master, you're the guru, you are the leader, you are everything! And, to understand is to transform what is.
For example: (1) As if governed by Newton's First Law of Motion, an institution will resist any change in its current direction; (2) Just as work expands to fill available time, corporate projects or acquisitions will materialize to soak up available funds; (3) Any business craving of the leader, however foolish, will be quickly supported by detailed rate-of-return and strategic studies prepared by his troops; and (4) The behavior of peer companies, whether they are expanding, acquiring, setting executive compensation or whatever, will be mindlessly imitated.
And let me say this as a politician I can promise you this, political leaders will never take risks if the people do not push them to take some risks. You must create the change that you want to see.
Woe betide the leaders now perched on their dizzy pinnacles of triumph if they cast away at the conference table what the soldiers had won on a hundred bloodsoaked battlefields.
