Embrace the principle of ‘Kaizen,’ a commitment to constant improvement and refinement. This pillar isn’t just about elevating one’s tennis game; it’s a holistic approach to life. It promotes the idea that we can always better ourselves in small, incremental steps — whether it’s perfecting a backhand or enhancing our daily habits.

Inner Fire

Awakening the inner flame speaks to the resilience and passion required not just in sports but in all of life’s pursuits. This pillar could focus on fostering the inner drive and tenacity that helps individuals push through challenges, bounce back from setbacks, and maintain a burning desire to achieve their dreams.

Respect & Love

The final pillar could highlight the importance of balance and harmony — respect and love for the game, oneself, and others. This encompasses sportsmanship, self-care, and community. It’s about nurturing a loving attitude towards one’s journey and those who are part of it, recognizing that personal growth is as much about internal harmony as it is about external achievement.

Your greatest journey begins with 'Keywhole'—unlocking the infinite within.

Embrace the now; your journey to wholeness begins with the abundance of today. Let ‘Keywhole’ guide you to unlock the infinite within, and embark on your greatest journey—an opportunity to tap into your full potential.

Hi Bastiaan. A quick note to say that after attending your courses, i achieved one of the items on my "fridge door bucket list" for 2022! I ran the half marathon in Amsterdam. Your courses in Weesp last spring, certainly were a factor in me achieving this. So thanks a lot for that. And the bonus was that i "smashed" my under 2 hour personal, with a time of 1:54:47. Thank you very much for the positive impact your courses & support had!

Hi Bastiaan. After participating to your workshops i gained much more awareness of the power of my thinking. I learned that positive thinking influences the way we are on the tennis court, it influences the way we are in life. Thanks to your inspiring work I have taken big steps in taking control of my thoughts, emotions and my behaviour. I received the tools to realise my goals and dreams. I am motivated to become the BEST version of myself.
