It takes exceptional wisdom to understand one's own motivations, but maybe I can list some of the components. This obligation should neither be under-estimated nor undermined by tenure. A second motivation is belief in shared governance. The AC4 is all about shared governance. It includes administrators who seek and manage resources, faculty members who control the curriculum and direct most of the research, students who enrich our lives and pay our salaries, and staff who make it all happen.
Shared governance is about respect, shared values, and a shared mission.
It depends on participation. Beyond this short answer, though, is an opportunity. There were tough and lonely times during this process but the overall results, and their eventual widespread acceptance by the Academic Senate, are a shared achievement that is important to me. My initial and overriding aim, of course, is to establish the Council as a valuable part of our shared governance structure, and this by itself is challenge and achievement enough. At this time, I don't know what, if any, other overarching issue will emerge.
