Here's why: You can't fix a systemic problem with isolated solutions.
Broken breathing isn't just a sleep problem.
It's not just a training problem.
It's not just a focus problem.
It's a cascade failure.
Poor sleep → Dopamine crash → Mouth breathing during training → Oxygen inefficiency → Poor recovery → Worse sleep → Deeper dopamine depletion → Autopilot behavior → No discipline → Cycle repeats.
Every isolated solution you tried fixed one piece while the system kept failing.
That's why discipline apps don't work when you're sleep-deprived.
That's why training harder doesn't work when you're oxygen-starved.
That's why supplements don't work when your breathing is broken.
You weren't fixing the foundation.
You were decorating your own collapsing tomb.
