The Truth About High Performance.

Most people don’t underperform because they’re lazy or lack ambition. They underperform because they’re out of alignment. Their thoughts are scattered. Their emotions are unchecked. Their energy leaks in all directions.

They want more, but they’re stuck in overthinking, perfectionism, or outdated beliefs.
They push harder, hoping that more effort will lead to better results.
But it doesn’t.

Here’s what most people were never taught:
High performance isn’t about doing more — it’s about being more. 
More focused.

More present.
More connected to your power.

Whether you’re an athlete, entrepreneur, or visionary…
Your mind is your most powerful asset.
Train it, and you’ll unlock a level of performance that feels effortless, inspired, and free.

Because when your thoughts align with your vision… Your emotions become fuel. Your actions gain clarity. And your results begin to reflect the person you were born to be.

Master your inner game. Perform at your highest level. This is where the extraordinary begins. 

The Science of Mindset – and How I Discovered Its Power.

When I discovered my passion for psychology, NLP, and the power of the mind, everything changed. I realized something most people never learn:

You’re not a prisoner of your thoughts, your past, or your emotions. Your mindset isn’t fixed—it’s programmable.

Once you understand how it works, you can condition yourself to rise in every area of life: sport, business, health, happiness, performance.

Your mind is a supercomputer.
Your thoughts are the software.

If you’re running outdated code—fear, doubt, perfectionism—your life will show it.

 

Your Mindset Is a Muscle — Here’s How to Train It.

Most people know what they want — but they haven’t trained their mind to support it. Old beliefs, fears, or doubts hijack their focus. They prepare their body, their business, their goals… But they forget the most powerful performance system they have: their mind. Here’s the truth:

Mental training is not optional if you want to rise to your next level. It’s the difference between:

  • reacting or responding

  • pressure or presence

  • self-sabotage or self-mastery

Train your mind like an athlete trains their body — and watch every area of your life level up.

What If You Could Perform at Your Highest Level—Every Day?

Most people train their bodies, but forget to train the one thing that controls everything—their mind. They work harder… but still feel stuck. They chase success… but carry stress, doubt, and inconsistency.

But what if you could build a mindset that fuels clarity, confidence, and consistency—not just sometimes, but every day?What if you could tap into flow on demand… And become someone who leads, creates, and performs from power—not pressure?

That’s what high-performance mindset coaching is all about. And that’s what I help you unlock—on the court, in your business, and in your life.

High Performance Coaching has been a game changer for us.

As a parent of a passionate youth tennis player, I want my son to thrive on court and off the court, but often we face challenges which are beyond  a great forehand or a good drop shot. This is where Mental Coaching has been a game changer for us. Mental Coaching with Bastiaan has transformed my Son’s emotional struggles and has helped him extend his self-confidence, Self-belief  and build mental toughness as a Player.

 

My Son Rijker, 11 years old, used to struggle with self-confidence and doubting his capabilities on court. Bastiaan has showed him and guided him how to deal with those emotions. Bastiaan and Rijker set small goals to work with every session, Rijker learned how to manage his emotions, build resilience and maintain focus during crucial moments. Bastiaan has invested his time to understand Rijker as a person and came out with personalized  route to help him succeed not just as a youth tennis player but also in life. Bastiaan would always keep in touch with Rijker to give coaching from a distances when necessary.

 

Mental Coaching has been a total transformation for Rijker. These tools that he has developed and learned will continue to enrich his life and will be a forever life tool. Thank you Bastiaan!!!!

Bastiaan's workshop made me realize how powerful our mindset truly is—on the court and in life. His inspiring approach helped me become more aware of my thoughts, emotions, and behavior. I now actively use positive thinking, growth mindset tools, and practical strategies like worksheets and emotional anchors to stay focused and empowered. The blend of theory and on-court practice works brilliantly.

This journey gave me the tools to reach my goals and enjoy the process. I’ve learned to stay present, think in possibilities, and choose the emotions I want to experience. Truly transformational and highly recommended! Thank You Bastiaan!

Elias Becker

My son Elias has attended a few of Bastiaan’s workshops for kids.  The courses have been a game-changer for my 8 year old son’s tennis journey.  With simple yet powerful approaches to mental coaching he has helped Elias control himself emotionally and think positively on the court.  

Through simple techniques like setting small goals and creating personalized  music playlists, Bastiaan has enabled my son to take charge of his thoughts and emotions and enhance his focus and performance.  His ability to simplify complex concepts into actionable steps tailored to young athletes makes it not only educational but fun . Not only has my son’s mental skills improved on the court but he has also developed invaluable life lessons that extend far beyond tennis.

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!
