 I've learned many lessons, but I've learned the following three key lessons. When you're trying to deliver innovations that address gross inequalities and injustices, you have to understand uncomfortable truths and histories that may actually reflect poorly upon your own country or upon your own ancestry. I am a big believer in aid, a big proponent of it, but we have to understand that aid often goes wrong because we forget about that deeper, uncomfortable history. A second lesson that I've learned is the importance of talent. As a healthcare organization, most of what we do is human resource management. The healthcare itself is relatively simple, relative to the big challenge of recruitment talent management. The third lesson has been about iteration, embracing failures, embracing mistakes, embracing the misguided thought patterns that we had. I sort of almost cringe at some of the decisions I make, the way I thought about the world, the way I thought about the problem, the way we went about solving these problems that we were seeing. I try to take those as lessons and as points of reflection for improvement so that we can learn how to be better and that we look at ourselves a year from now, five years from now, and we can again sort of cringe, laugh, cry at all of our mistakes, but know that we're in a better place than we were before.
