What should I ask John Amaechi?

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

John Uzoma Ekwugha Amaechi // ^ⓘ, OBE (/əˈmeɪtʃi/; born 26 November 1970) is an English psychologist, consultant and former professional basketball player. He played college basketball for the Vanderbilt Commodores and Penn State Nittany Lions, and professional basketball in the National Basketball Association (NBA). Amaechi also played in France, Greece, Italy, and the United Kingdom. Since retiring from basketball, Amaechi has worked as a psychologist and consultant, establishing his company Amaechi Performance Systems.

In February 2007, Amaechi became the first former NBA player to publicly come out as gay after doing so in his memoir Man in the Middle.

John has a new book coming out, namely It’s Not Magic: The Ordinary Skills of Exceptional Leaders.  So what should I ask him?
