A model for reading the escalating severity of burnout signals your body sends. The 'feather' is a faint early cue (mild morning tiredness); the 'brick' is a mid-stage disruption (a blow-up argument, persistent frustration) weeks later; the 'dump truck' is a full-blown crisis months or years later (a health collapse, type 2 diabetes, getting fired). The goal is to build enough interoceptive capacity to notice and adjust at the feather stage, when correction is cheap.
Origin
Jonny Miller's own model, tied to his broader work on interoception and emotional debt. He references Andy Johns' Lenny's Podcast episode as a real-world illustration of small ignored signals compounding into an unsustainable life.
Core principles
- 01Burnout signals escalate in severity the longer they're ignored
- 02The cost of correcting rises sharply from feather to brick to dump truck
- 03Your ability to notice the feather depends on your interoceptive capacity
- 04People with large nervous-system capacity can suppress signals for years, making the eventual crash worse
How to run it
- 1
Learn to feel the feather
Attune to faint early cues: waking mildly tired or a little exhausted, small dips in mood or energy that are easy to dismiss.
Pro tip Interoception training (APE, NSDR) is what makes these signals legible in the first place.
Watch out These signals are subtle by design; without deliberate body awareness you will not register them.

Recognize the brick
If ignored, signals escalate weeks later into disproportionate reactivity — a fight or argument, feeling frustrated and terrible, losing your cool, worse sleep, strained relationships.
Pro tip Intimate relationships and work relationships are the classic places this reactivity first shows up.

Adjust before the dump truck
Once you notice a feather or brick, make changes then — reduce load, add recovery — rather than pushing through to a months- or years-away crisis.
Watch out The dump truck can be a long-term health crisis where no amount of money or time repairs the damage; waiting is the expensive path most first-time sufferers take.
In the wild
Jonny describes how people with large nervous-system capacity normalize being 'always on,' buffering stress for 5-10 years until a fuse blows — exhaustion, an inability to get off the couch — because they never noticed the earlier signals.
→ A far more damaging, sometimes irreversible collapse than if they'd corrected at the feather stage.
Common mistakes
Normalizing 'always on'
Treating a never-relaxing, never-downshifting mode as normal masks accumulating signals until the crash is severe.
Mistaking high capacity for safety
Being able to keep going for years without visible breakdown just means the dump truck arrives bigger and later.
Is it for you?
Best for
Ambitious operators in high-pressure startup environments who want to avoid first-time burnout by catching it early
Not ideal for
Someone already in acute crisis who needs recovery and professional support now, not early-warning theory
From the transcript
“I call the the feather brick dump truck phenomenon”
“the feather might be waking up in the morning and feeling a little bit tired”
“three or four weeks later, you you have like a fight with someone or an argument”
“the the dump truck is a month later or even a year later, there's like a full-blown health crisis or you develop type two diabetes”
“ideally you want to notice when it's the feather and then make adjustments”
