After the book
Acknowledgments and Colophon
Thank you to the founders, course participants, colleagues, collaborators, and readers who, over the years, have allowed my thoughts to meet their reality.
A thought does not become stronger by being protected. It becomes stronger when someone asks the question you hoped to avoid or points to the place where the explanation has become more elegant than the problem.
Thank you to those who shared their mistakes, doubts, and experiences without first making the story look tidy. Thank you to those who disagreed. And thank you to the readers of the first edition, who made it possible to return to the book with more experience, fewer certain answers, and a clearer direction.
This edition is still written from the position of one person. Its value begins only when you meet it from yours.
Thank you.
