“Harry Kramer is the former chairman and CEO of Baxter Healthcare. I was hosting a virtual event. Harry, today, he’s retired from Baxter Healthcare, and he is a clinical professor of leadership at Northwestern University, and he runs a private equity company. I said, ‘Harry, in your 40-year career, leading thousands of people globally, what is the one thing you share with individuals as the key thing to play to win?’ He said, ‘Simon, you have to self-reflect.’ I said, ‘Unpack that for me.’ He said that every day for the last 40 years, he’s asked himself these three questions. How did I grow today? What difference did I make today? What am I going to do better tomorrow?”
