“Special thanks are due to Ivan Kronenfeld, my friend and most unlikely of renaissance men. It was at his insistence that I wrote a memoir, and he persisted despite my first refusing and then ignoring his entreaties.
But he is tougher than I, and he prevailed.
His is a most successful technique, espoused by Sun Tzu and practiced with great success by Mao Tse-tung: jab, run, jab, rope-a-dope, jab again and again – and eventually wear the poor guy down. This book was his idea, and so if it isn’t any good, blame Ivan”

-Colonel Jack Jacobs (Ret.)

In addition to producing many books, Ivan was an author, having written The Secret Life of Dr. James Miranda Barry with his wife Anne Byrne. His advice and guidance has been acknowledged in several books notably You: The Owner’s Manual co-authored by Dr. Mehmet Oz and Turbulent Souls by Freakonomics co-author Stephen Dubner.

“To Ivan Kronenfeld, who asked me two years ago why I never talked about men.

Not only did he introduce me to a whole spectrum of spectacular soldiers, boxers, policemen, educators and lawyers, but he reminded me when this book was finished to thank them all for their spectacular bravery and their uncompromising willingness to do all the difficult and brutally hard things we ask of men.”
