I don't want this to sound flippant at all, but it reminds me of what they say about advertising, “repetition, repetition, repetition, and colour”. It's important to very dogged in this work. The issues are big. It's a large organization. You may think you've addressed a problem because you've resolved an issue at one institution in one corner of the country, but that problem has probably been manifesting in another institution in another corner of the country, and yet you have to chase it down.
I'm very fortunate. I have a tremendously competent high-performing team in the office. It's small, but they punch way above their weight class. I hope whoever comes next recognizes that that team will depend on that person to have the same commitment to stay focused and to be vocal, and not shy away from some of the difficult discussions that we've certainly had to engage in over the last decade.
