# Credits

To my wife Angela, who brings me back to earth but never lets me down, dad, mom, brother, family in-law, my loyal writing companion and dog Oscar, friends, supporters, and most notably, Philippa (Pip), Atticus (Abe), Halcyon (Cy) and Hart, who I hope will use this book to make sense out of the world and lead in the age of AI with the deepest form of Lean. May you heed the words of André Paul Guillaume Gide: 

> #### “Believe those who seek the truth; doubt those who find it; doubt everything, but don’t doubt yourself,”
>
> (found in, “Ainsi soit-il; ou, Les Jeux sont faits,” p. 174 (1952)).
