Based on a conversation between Reeva Misra (CEO WONE) and Mindy Grossman (Former CEO Weight Watchers).

For decades, leadership effectiveness has been explained through two forms of intelligence.
IQ, a measure of your ability to reason and solve problems.
EQ, a measure of your ability to understand and navigate emotions.

Both remain essential. But in today’s high-pressure, high-velocity world, they are no longer sufficient on their own.

Leaders are operating in an always-on, hyper connected environment where speed is rewarded, complexity is compounding, and uncertainty - economic, social, geopolitical - has become a permanent backdrop.

Add artificial intelligence accelerating the pace of change exponentially, and it’s no wonder leadership today feels less like a marathon and more like a series of unending sprints.

In this environment, the leaders who thrive are not simply the most intelligent or the ones pushing hardest. They are the ones who stay clear, focused and intentional under pressure.

This capability requires a third form of intelligence: Stress Intelligence (SQ). The ability to read your body’s signals and respond deliberately rather than overriding them. 

It allows leaders to notice shifts in physiological state, energy, tension, focus, and reactivity, and to use that information to guide decisions and behavior. Without this capability, even highly intelligent and emotionally skilled leaders can become reactive, cognitively narrowed, or misaligned under pressure.

And right now, it may be the most critical leadership skill of our time.

Why Stress Intelligence matters for leadership today

For decades, leadership culture rewarded endurance. Push through. Power on. Ignore the signals. That model has reached its tipping point.

Stress has long been treated as something to suppress or override in leadership. A sign of weakness, inevitable but inconvenient noise best ignored. In reality, stress is a physiological and psychological response signaling vital information. The best leaders don’t tune the information out; they use those signals as data to stay at their best time and time again.

This distinction is subtle, and it requires acute self-awareness.

Throughout her career, Mindy Grossman has led companies through moments of extraordinary pressure, such as taking HSN public in August 2008 just weeks before the collapse of Lehman Brothers and transforming Weight Watchers during the early days of the COVID crisis. In each moment, the instinctive response could have been the same: retreat, cut aggressively, or simply endure. Instead, Mindy made deliberate high stakes decisions that altered the trajectory of these businesses.

In March 2020, that pressure became existential. Almost overnight, 30,000 in-person Weight Watchers workshops across 13 countries were forced to shut down. Revenue risk was immediate and obvious. But rather than narrowing the organization's focus to survival alone, Mindy anchored the response around a single principle: we cannot leave our members alone.

What followed was a six-day sprint to move every workshop online. Teams worked at extraordinary speed, not because they were pushing blindly, but because the purpose was unmistakable. They weren’t driven by panic, but by intention and clarity. Decisions were fast, not frantic. Bold, but not reckless.

The stress did not disappear, but it was interpreted correctly, as information rather than threat, and resilience emerged.

What Grossman describes as “resilient optimists” offers a useful way to understand a stress-intelligent response. It is the ability to fully acknowledge disruption without being consumed by it, and to choose, deliberately, to treat pressure as a catalyst rather than a threat.

Crucially, this mindset is not blind positivity. It is not about closing our eyes to reality or bypassing difficulty. Nor is it innate. It is built over time, as leaders train both mind and body to recognize stress clearly and respond with precision.

This capacity, to stay clear under pressure, is at the heart of stress-intelligent leadership.

From endurance to intelligence

Resilience is often misunderstood as toughness or stamina. In reality, resilience is not about enduring more stress. It is what grows when stress is recognized early and responded to intelligently over time.

At the right level, pressure sharpens focus, fuels creativity and enables bold action. Too much, and it overwhelms the nervous system, narrowing perspective and driving reactive behavior. The challenge is that everyone’s threshold is different, and those thresholds are not static. They shift with context, cumulative load, and time.

Highly effective leaders learn to notice what Grossman calls “twitchy signals”: subtle internal cues that something is off. Impatience, narrowing focus, rushing decisions, pushing people faster than they can follow. These are not flaws or leadership failures. They are early warnings. Stress-intelligent leaders treat those signals as data, responding with curiosity rather than defensiveness, and using them as opportunities to recalibrate and develop.

Early in her career, Grossman noticed that her drive to move quickly sometimes meant she wasn’t bringing others along. Once she became aware of it, she named it openly with her team. That self-awareness didn’t slow her or her team down, in fact, it made them more effective.

Knowing when to push and when to pause

The ability to read and respond to your body’s signals underpins another core component of Stress Intelligence: discernment.

As Grossman puts it, there is a difference between risk and suicide. Boldness is essential for transformation, and avoiding risk altogether is often the riskiest choice. But stress-intelligent leadership lies in knowing the difference between courageous risk and reckless persistence.

In organizations where leaders cannot admit something isn’t working, stress compounds silently. Fear replaces experimentation. Progress stalls, not because people lack ambition, but because they lack permission to pause.

By contrast, cultures shaped by stress-intelligent leaders normalize recalibration. People feel safe to take risks and equally safe to say, “This isn’t working.”

That willingness to step back, reassess, and pivot is not indecision but rather maturity under pressure. It’s why the next era of performance will not be driven by pushing harder but by listening sooner.

The leadership imperative ahead

Stress Intelligence represents a new leadership capability, one that determines how decisions are made, how cultures behave, and how performance is sustained over time.

As pressure and complexity continue to rise, leaders will increasingly be defined less by how much they can handle and more by how intelligently they respond. IQ and EQ still matter. But without SQ, both become fragile under pressure.

The leaders who will shape the next decade are those who can read their body’s signals, recognize their limits, and pause long enough to think with precision before they act. 

In a world that rewards speed, Stress Intelligence gives leaders something far more powerful: clarity.

And clarity, especially now, is your competitive advantage.
