A Field for Eccentrics
We are limited by our experiences. That is why it is important to study the experiences of others. We may disagree with the lessons they drew but the events are instructive.
A chief appeal of being a management consultant is that no field of study is useless. It is obvious that some subjects are richer veins than others but if you are alert you can find lessons hiding in the most unlikely of places. An innate curiosity helps to connect the dots and an unwritten part of the job's description involves detective skills. Although the client sees Problem A, the real source of difficulties may be Problems B or Z.
The ability to make that diagnosis can come from a variety of disciplines. Perhaps that is why the field has so many eccentrics.
