This book is dedicated to people who changed my lasting behavior.
These special people influenced my life forever:

My parents, who did not change my life or behavior;
they helped me discover it.

My coach, Mr. Henneveld,
who developed my top sport mentality.

My wife, Monique, who continuously challenges me in
developing as a human being.

My three kids, Max, Sem, and Fleur, who changed the reason
why I am on earth.

My brother, Kees, whose behavior I admire and use as a
mirror to develop mine.
