Iβm Bastiaan Kollen.
I grew up on the tennis court β playing, learning, making friends, and enjoying the game. Sport gave me joy, confidence, and discipline. But in my twenties, I discovered something just as powerful: the mindset behind performance.
I became fascinated by why some athletes block under pressure, while others rise beyond themselves. And I realized:
Β
Mindset makes the difference.
Β
Since then, Iβve dedicated my life to understanding the human mind β through NLP, psychology, coaching, and high-performance training.
Today, I help athletes, coaches, and professionals with the tools I once wished I had: confidence, emotional control, focus, and above all, joy in the game.
Β
My mission is simple: To help people train their minds β so they can become the champion of their own game & life.
βCoach, isnβt everything just the story you tell yourself? If I tell myself Iβm old, Iβll start to feel old. But if I tell myself Iβm growing and that Iβm worthy, then Iβll play that way too.β
β Taha
βThe mental coaching with Bastiaan was exactly the breakthrough my son needed β both on and off the court.β
β Rijker Fouwels
βThese workshops have been a true game changer for my sonβs tennis β and for his life.β
