Following our formal education, we inevitably become teachers and
students of each other. Signifi cant numbers of people cross our paths over
the course of our careers, whether directly and in person or indirectly
through the written word. Many have thus contributed to my education.
While it is not possible to acknowledge here all of the many mentors,
coworkers and colleagues who have contributed to my experience and
thus to the writing of this book, I will attempt to do so. For those I may fail
to note, I ask your indulgence, but please know that you are acknowledged
here with intent.
