Leslie,Having served in a Deputy/Assistant role for 11 years now, I'll tell you that it can be a position that continually offers new and interesting challenges and opportunities for growth. Here are two key ideas that I would have told myself when I started, knowing what I know now:1. Focus on relationships and results - This ability is really the essence of any effective professional, and is especially true in our roles. I know I don't have the technical training and expertise of the department heads that report to me. Also, relying on the formal authority of my position may be necessary at times, but I've found that it is not useful in building and sustaining a great organization over the long-term. Relationships and results are what matter most.2. “Mind the Gap” - Yes, borrowed from London's Tube, it's become a bit of a mantra of mine. There are many ways of understanding this idea of "the Gap". It could be the gap between current and potential performance of an individual or team. Or it could be the gap between administrative sustainability and political acceptability (you can Google "Dr. John Nalbandian and the Gap" if you're not familiar). Regardless, viewing the role of Assistant/Deputy as being able to understand and help "bridge the gap" as a key function of the job has been extraordinarily useful to me over the years. Thanks for giving me the chance to weigh in. Best wishes.
