One-on-one mentorship

Stoic philosophy
for those who
compete seriously.

Not performance hacks. Not quick fixes. A practice built on 20+ years of competing, coaching, and studying what actually holds people together when the pressure is on.

For athletes who want composure under pressure. For founders who want clarity in chaos. The principles are the same.

"You have power over your mind — not outside events. Realise this, and you will find strength."
Marcus Aurelius, Meditations

Not therapy. Not motivational speaking.
Stoic practice.

The Stoics weren't interested in feeling better. They were interested in performing better — and in living in accordance with what they could actually control. That's the frame we work from.

I

Focus on what you control

Most anxiety — in sport, in business, in life — comes from trying to influence outcomes that aren't yours to own. We learn to redirect energy toward what actually moves the needle: preparation, attitude, effort.

II

Build composure as a skill

Composure isn't a personality trait. It's a practice. We work on the mental routines, language patterns, and recovery habits that keep performance consistent — especially when the stakes are high and things go sideways.

III

Show up every single day

The Stoic tradition is fundamentally a daily practice — small acts of discipline, reflection, and presence. We build those habits into the structure of your week so the philosophy stops being abstract and starts being real.

Athletes. Founders.
People who take the long game seriously.

The contexts are different. The underlying challenges — managing pressure, staying clear, competing consistently — are the same.

Athletes & competitors

Whether you play professionally or seriously compete as an amateur — the mental side of performance is where most matches are actually won and lost.

  • Pre-competition nerves and mental recovery
  • Sustaining focus over a long season
  • Dealing with injury, loss of form, transition
  • Building routines that hold under pressure

Founders & builders

Building something from scratch in a world that changes constantly requires the same composure tennis taught me: decide fast, stay present, and don't catastrophise.

  • Clarity when decisions are hard and stakes are high
  • Managing uncertainty without burning out
  • Building mental structures for sustained output
  • Staying grounded when the company depends on you
Maximilian Breboeck in conversation

The conversation is where it happens.

Most of the breakthroughs I've seen in mentorship don't happen during the structured sessions. They happen in the casual conversations — over a coffee, during a walk, when the pressure is off and the real questions finally surface.

That's the dynamic I try to create. Not a seminar. Not a coaching script. A real exchange between two people who take the work seriously. I bring the frameworks; you bring the actual problems. Together, we figure out what to do with them.

If any of this resonates — send a note. The best mentorship relationships start with a simple introduction.

Sessions are one-on-one, by invitation. If you're serious about the work and the questions above resonate — send a note. We'll take it from there.
