Performance starts within.
Physiology-first tools for leaders who perform under real pressure — without burning down the nervous system to do it. The newsletter, the workbook, the resets, and the research, in one place.
01 Start here
One idea a month, worth your attention
One usable idea about leading from a regulated nervous system, roughly monthly. No daily drumbeat — when it's worth sending, Abi sends it.
02 The core premise
Leadership is shaped by three internal conditions
Most development trains skill and mindset. Very little trains state — this work does. The nervous system underpins all three.
State
Your physiological and emotional baseline.
Capacity
Holding complexity without collapsing or controlling.
Signal
What your presence communicates to others.
The outcome is better decisions, clearer communication, and sustainable performance.Abi Harmon · Founder, House Harmon
03 Free resource
The Nervous System Performance Workbook
A practical framework for leading under pressure — the science of state, capacity, and signal, translated into a 30-day arc you can actually run.

04 Practice
Audio resets
Three guided breathwork resets — put one on before a hard meeting. Longer exhale than inhale; that's the whole trick.
05 The research, in plain language
