Practice
You cannot learn this at a desk.
The method puts people back at the beginning of something, on purpose. Being a beginner is the one condition where the drift is impossible to hide from yourself.
Experienced people have learned to look competent under pressure. That is a real skill, and it gets in the way. Hand a superintendent a pair of trail shoes and a steep hill, or a guitar, or a sketchbook, and within twenty minutes you can watch Scale, Slow build, Visibility, and Depletion play out in real time, in a body, with nothing at stake but pride. Then we talk about Monday.

Three ways in

Physical
Trail running and walking on real terrain. Hills are Scale. Weather is Volatility. The second mile is Slow build. Pace is the clearest teacher of regulation there is, because your body tells you the truth about proportion whether you want to hear it or not.
Most in-person work starts here, on the trails and stone walls of the land where I live. You do not need to be a runner. You need to be willing to be bad at something in front of other people.

Musical
Learning an instrument from zero, in front of other people. Weeks of sounding bad before it sounds like anything. Nobody fakes their way through this, which is the point.
Music teaches Slow build and Visibility faster than almost anything else, because the gap between what you want to hear and what you are producing is audible to everyone in the room.

Artistic
Drawing, building, making something with your hands that will be looked at. The gap between what you see and what you can do is Scale you can hold in your hand. Making something and showing it is Visibility. Throwing out the first three attempts is Repair.
Why a beginner
Three reasons.
The drift is honest
When you are new at something, you do not have the skill to cover for what pressure does to you. You surge or you freeze and everyone, including you, can see it.
The stakes are low
Nobody’s job, child, or reputation depends on how you do on the hill. That makes it safe to notice, name, and talk about what happened without anyone getting defensive.
The body remembers
Pace, breath, and effort are things you can feel. Once you have felt proportion on a trail, you have a reference point for it in a meeting.
The intellectual side
The practice is not only physical. We use the arenas and patterns as a shared language, the four timings as a mirror, and a structured process for finding what holds a pattern in place. People read, write, and think hard. But the language only sticks when it has been felt first. We go outside before we go to the whiteboard.
