Perspective

What I see, and where I see it from.

How I look at people and at digital tools, the method that comes out of it, the research I lean on, and what I write about it. You will always know whether you are reading a fact or my point of view.

I don't promise to be right. I promise that what I say will be useful.

I can be wrong. What I say, I have either lived or checked, and I tell you which.

Before anything else

Reality and truth are not the same thing

This is the distinction I use in coaching. Mixing them up means selling an opinion as a fact.

Reality

What can be measured

Measurable, countable, not open to interpretation.

I state it as a fact, and I give its source. If I can't source it, I don't write it as a fact.

Example 16,207 commits between November 10, 2025 and September 25, 2026, read on GitHub.

My truth

What I see

Subjective, personal. Mine is not yours.

I state it as a point of view, and I own it. Do what you like with it, including nothing.

Example Going along with people is not kindness.

On this page, whatever belongs to my truth carries its mark.

Where I look from

What makes me see what I see

My perspective comes from how I function. Naming it does not put me in a box: it explains where my way of thinking comes from, and what I bring.

  • Intellectually gifted

    What it means I think in branches: one idea opens ten, and I need meaning to move forward.

    What it brings I quickly see links between things everything keeps apart, and the cause behind the symptom.

  • Highly sensitive

    What it means I strongly perceive what is going on in others, including what is left unsaid.

    What it brings I feel where things get stuck, often before I'm told.

  • Multipotentialite

    What it means Several trades, several passions: design, entrepreneurship, coaching, gaming, code.

    What it brings I connect worlds that don't talk to each other, and borrow from one what the other lacks.

  • Projector My truth · Human Design

    What it means I guide best when I'm invited. My intuition comes all at once, once, and I say it in the moment.

    What it brings An outside view, one that sees how the other person works without getting lost in it.

If you recognise yourself, good. If not, it says nothing about you.

What I see

Four things I see, and say

These are convictions, not proof. They come from 21 years of entrepreneurship, more than 13 years of coaching, and my own life.

  • My truthWhen a tool doesn't fit you, the problem isn't necessarily you.

    Every tool imposes a single way of being, the same for everyone. Many people blame themselves for what is a flaw of the tool.

  • My truthGoing along with people is not kindness.

    Kindness means saying things even when they disturb. I can be hard on a situation, never on the person. And I give you back your part.

  • My truthIdentifying is not categorising.

    Naming a way of functioning helps you understand it, and use it. What I refuse is locking someone in a box, or deciding for them what they are.

  • My truthThe “what for” first. The how always follows.

    The “what for” is a thing's reason to exist, its purpose. When it is clear, the how shows up by itself to serve it. I always start there.

The method

Michi no Kata, the Way of Form

How I go from the friction I see to the delivered solution, with no one in between. The same path works for code, gaming, coaching and business.

  1. See the friction I start from your real situation. What really resists is often invisible from the inside.
  2. Design the answer The answer takes shape from your reality, never from a model applied to everyone.
  3. Build the solution I don't stop at advice. What is thought through gets delivered, with nothing lost in between.

Who does what

  • Me I see, I design, I decide. I am not a developer: I am the architect.
  • AI It writes the code, under my direction and within my method. It proposes, I decide.
  • The guards They check every change and block what doesn't pass. Neither I nor the AI get around them.

Quality is not a step. It is in every gesture.

The Japanese art of making: the craftsperson doesn't add quality at the end, it is part of them. Every change to my tools goes through these five gestures, and here is why each one exists.

68 automatic guards watch over every change Reality Counted on October 10, 2026 by the check that opens each of my work sessions.

  • The check before the code The test that proves it works is written before what it checks. Otherwise the test ends up checking what the code does, not what it was meant to do.
  • Nothing taken on trust Every version, every tool is checked on the day, never from memory. An AI's memory is dated. The world has changed since.
  • Security from day one No secret in clear text, no access left open. A flaw added “for later” often stays forever.
  • A second look An independent review looks for the flaw, not for approval. Whoever wrote it can't see their own blind spots.
  • Proof, not promise “It should work” doesn't exist: it runs, or it isn't finished. A promise costs nothing. Proof can be checked.

Research

What I lean on

I read a lot, and I file what I read. Here is the base, then the references behind my coaching, each with its type of source.

  • 846 notes in my knowledge base, across 18 domains
  • 4,254 distinct web sources cited
  • 126 scientific studies identified
  • 69 references for coaching

From the most measured to the most personal

  1. Published study Measured reality Reviewed by other researchers before publication.
  2. Report An organisation's data Figures published by an institution or a company.
  3. Book An author's model Often grounded in studies, but it is their reading.
  4. My truth A thinking tool I use it, with no scientific validation.
