The hardest skill isn't adding things. It's noticing what to remove. Every system accumulates noise over time, and the noise starts to feel structural. You forget it wasn't always there.
This applies to code, to routines, to beliefs. The thing you built around a constraint that no longer exists keeps running, keeps costing energy, keeps shaping decisions. Nobody questions it because it looks load-bearing.
Stripping back is uncomfortable because removal feels like loss. But most of the time what you're losing is friction you'd stopped noticing. The system gets lighter. The signal gets clearer.
The discipline is in the audit: what here is still earning its place? Everything else is debt wearing a disguise.
