Most people do not need more information.

They need a clearer way to train their character. They need something practical, repeatable, and grounded enough to use on a real day, under real pressure. That is what the Ten Rules are for. They turn dojo philosophy into action.


What exactly is the D.o.j.o?

Martial arts is not the destination — it's the operating system for how we train leadership: physical, honest, repetitive, and grounded in a clear code.

  • “Everybody has a plan, until they get punched in the face” – Mike Tyson

    It is not only having discipline, rather it is about but disciplining your:


    Mindset, Emotions and Actions.

  • Are you the Master or the Apprentice?

    From which Identity are you observing your current reality,?

    Learn to understand your patterns, habits, actions and world view.

  • Life's a game, Play!! - Cor van Drieberge

    Jogar — from the Portuguese verb meaning to play.

    In capoeira (and other martial arts) you don’t learn only by fighting,  you learn most by playing the game.

    In the animal kingdom, lessons are learned through play, simulation and movement.
    Theory works best when you “play” it. Experiment, get best practices and pick the lessons that work for your leadership.

  • “Leaders must own everything in their world. There is no one else to blame.” - Jocko Willink

    Learn to stop making excuses, take action and responsibility on your personal development

Where the D.o.j.o Shows Up!

  • Teaching and Coaching D.O.J.O

    The DOJO Framework starts from the inside, building character that sustains everything else.

    Identity before strategy.
    Who you are shapes what you do.

    Mind and body. Physical discipline and mental resilience train together.

  • Coaching for Young Leaders

    "Leaders are made, they are not born.” – Vince Lombardi

    In the DOJO you will work on your (personal) leadership, developing skills, mindset and building relationships to grow as a leader

    You can't lead others until you lead yourself.

  • Sparring partner & coach

    "If you're always the sharpest blade in the room, you stop getting sharpened. Average hangs with admirers. Elite seek sparring partners." - David Kitchen

    In martial arts you test your skills by sparring, all with the aim to understand your current level, tackling blind spots and understanding which skills you need to work on.

The Dojo is not the destination.

It is the place where you develop, practice, repeat and create awareness.

The ethic behind the rules

The dojo is more than a place. It is a standard. Respect, discipline, clarity, courage, and ownership shape the way you train, think, and lead. This guide is built on that ethic, so the rules do not just sound good — they can be lived.


What’s inside the guide?

A simple structure. Easy to read. Easy to apply.

  • A short introduction to the mindset behind the guide — the values, standards, and philosophy that shape how you train yourself in leadership and life. This is where the deeper code begins.




  • The core of the guide. Ten direct rules to help you build more discipline, clarity, resilience, ownership, and character in the way you live, work, and lead.


  • A practical section you can print and fill in by hand so the rules do not stay abstract. Writing things down creates a more tangible level of reflection, application, and accountability.

  • Once you finish the guide, you will know where to go next — whether that is staying with the free material, joining Dojo Dispatch, or stepping deeper into the work with Cor.

Who is the dojo for?

For young professionals who feel like they're "in formation", stepping into more responsibility, but not interested in generic leadership fluff.

  • Question: "Am I actually a leader or am I faking it?"

    Just promoted or leading projects for the first time. Technically sharp, unsure how to lead humans without losing yourself.Ready to transform your mindset?

  • Question: "Why do I keep self-sabotaging?"

    High drive, low structure. Great at output, shaky under pressure. You want discipline that frees you instead of burning you out.

    Let’s spar and grow your business.

  • Question: "How do I make my second chapter stronger than the first?"

    Changing lanes or levelling up. Experience is there, but your identity and standards need a harder, cleaner edge.

    Ready to take charge of your health?

The dojo doesn't care about your excuses. It cares about your progress.
