Practices that may help

1. The Zone of Optimal Functioning: Hanin’s IZOF Model
   Yuri Hanin’s Individual Zones of Optimal Functioning (IZOF) model holds that each athlete has a unique pre-competition anxiety range within which performance is best — and that this range, and the anxiety level that produces it, varies significantly between individuals. The practical implication is that there is no universally optimal arousal level: some athletes perform best when highly anxious, others when calm. The work is to identify your personal zone and develop practices to enter it reliably.
2. The Ideal Performance State, Made Practical
   The Ideal Performance State (IPS) is Jim Loehr and Tony Schwartz’s term for the specific combination of physical, mental, and emotional activation at which a performer reliably produces peak output. The IPS is individual-specific — what energizes one performer paralyzes another — and is accessed through deliberate energy management rather than through hoping to "get in the zone."
3. Treat recovery as a performance investment, not a reward for finishing
   Schedule recovery as deliberately as training — stress without recovery produces breakdown, not growth.

4. Oscillate deliberately between full engagement and full recovery
   Treat disengagement between performances as a skill to develop, not an indulgence to manage.

5. Design for resilience, not just peak efficiency
   Optimized systems are fragile; resilient systems absorb disruption and recover without collapse.

6. The Yerkes-Dodson Law: Finding Your Optimal Performance Zone
   The Yerkes-Dodson law describes an inverted-U relationship between arousal (stress, activation, anxiety) and performance: too little arousal produces low performance due to disengagement; too much produces performance breakdown. The optimal level of arousal is in the middle — and it varies by task, with complex or novel tasks requiring lower arousal than simple, well-practiced ones. The basic relationship is well-replicated, though the precise "optimal point" is harder to measure.
7. Analyze your best days — not just your failures — to identify what drives success
   When performance is above target, investigate what made it so: replicating peaks is as important as preventing troughs.
   Feedback Loops and Behavior Change
8. Expand the IZOF profile to include positive and negative emotions
   Map which emotions — not just anxiety — are functional for your performance, and which are dysfunctional.

9. Map your personal Ideal Performance State
   Identify the exact mental, emotional, and physical conditions under which you perform at your best.

10. Audit your life against PERMA
    Check well-being across all five pillars — emotion, engagement, relationships, meaning, accomplishment.

Does this sound like the set of challenges you might be facing?

• I treat rest as something I only earn after everything else is done, so it’s the first thing I cut→
• I’m never fully on and never fully off→
• I pack every minute of my day until it’s perfectly optimized, and then one sick kid or one surprise meeting topples the whole thing like dominoes→
• Some weeks everything just clicks and I’m killing it, and I have no idea why→
• Everyone tells me to get calm and positive before I perform, but honestly some of my best moments came when I was actually a little angry or on edge→
