What should I ask Arthur C. Brooks?

Yes I will be doing a Conversation with him.  Here is Wikipedia:

Since 2019, Brooks has served as the Parker Gilbert Montgomery Professor of the Practice of Nonprofit and Public Leadership at the Harvard Kennedy School and at the Harvard Business School as a Professor of Management Practice and Faculty Fellow.^[2] Previously, Brooks served as the 11th President of the American Enterprise Institute. He is the author of thirteen books, including Build the Life You Want: The Art and Science of Getting Happier with co-author Oprah Winfrey (2023), From Strength to Strength: Finding Success, Happiness and Deep Purpose in the Second Half of Life (2022), Love Your Enemies (2019), The Conservative Heart (2015), and The Road to Freedom (2012). Since 2020, he has written the Atlantic’s How to Build a Life column on happiness.

Do not forget Arthur started as a professional French hornist, and also was well known in the cultural economics field during his Syracuse University days.  And more.  So what should I ask him?
