Consider the 3 (or 2 or 5) meetings you've been to today. Consider the 3 project milestones just buttoned up—or the 3 on the near horizon:
Has the word "EXCELLENCE" per se been used as a basis for evaluating your actions? Could you personally call the outcome of each meeting or the nature of the milestone/s achieved or approaching "Excellent"?
Key idea: The "Excellence Standard" is not about Grand Outcomes. In Zen terms, all we have is today. If the day's work cannot be assessed as Excellent, then the oceanic overall goal of Excellence has not been advanced. Period.
That is, the "Excellence Watch" must be a daily affair—or you simply are not serious about the overall Standard of Excellence.
