Working definition
Place bumpers in the environment — phone wallpaper, contact names, sticky notes, calendar slots — so the ball cannot fall into the gutter even when you are tired.
How it works
Drift is the default. Drift and Sedimentation explains the universal phenomenon: focus erodes naturally toward the path of least resistance. The operational answer is not more discipline. It is environment design.
You installs bumpers — physical or digital — that catch the attention every time it slips:
- Phone wallpaper. The Battle of the week, displayed as the lock-screen background. Every unlock is a reminder, regardless of willpower.
- Contact rename. The three or four people you speaks to daily get a suffix that names the current training move — Marie · Calibration, Paul · Be Perceived. The Battle returns at every call.
- Notification slots. Two or three recurring phone notifications with the Battle question (see Calibration).
- Visible artefacts on the desk. A post-it, a card, a tally chart. The visual gravity of the artefact pulls the attention back without thought.
The image is the bowling-lane bumper or the horse-track drift rail. The discipline is not asked of you moment by moment. It is asked once, at the design moment, when the bumpers are placed.
Signature
The image is bowling-lane bumpers — the drift rail that keeps the ball from guttering while you still throw. Yann recurring: drift is default; the bumper is the system constraint you install before Monday — 2026-02-16.
Spatial split — drift (path of least resistance) versus bumpers (environment catches attention back to the Battle). Your move: Your move this week.

Your move this week
This week’s micro-action (24–72 hours):
- Install at least two bumpers tonight: change the phone wallpaper to a one-line reminder of this week’s Battle, and rename one frequently-called contact with the current training move as a suffix.
