Eliz Greene Is Interested in What the Results Don't Tell Us
Eliz Greene has spent more than two decades studying what it takes to perform under pressure, particularly when capable people are still getting the work done.
At 35, while seven months pregnant with twins, Eliz survived a heart attack. An emergency cesarean delivery and open-heart surgery followed. She held her daughters 17 hours after surgery.
That experience launched more than two decades of work exploring the connection between stress, health, and performance. Eliz conducted an original study of more than 4,000 people on job stress, is the author of Stress-Proof Your Life: High Performance Under Pressure, and has brought her work to corporate, healthcare, association, and leadership audiences across the country.
It also made her very interested in what we don’t recognize until later.
What do we wish we had noticed sooner?
Eliz spends her summer free time on sailboats on Lake Michigan, which turns out to be an excellent place to think about that question.
On a sailboat, conditions rarely care about the plan. More effort isn’t always the answer. And, as Eliz discovered after running out of fuel on a boat with a tank labeled for 36 gallons that actually held 30 and a gauge that couldn’t be trusted, our assumptions about available capacity aren’t always particularly reliable either.
That 20 percent difference became one of Eliz’s favorite ways to explain a concept she calls Capacity Optimism: the tendency to overestimate how much capacity we actually have available.
Because the same thing happens at work.

The Work Can Be Getting Done
While Something Important Is Changing
Capable people are remarkably good at compensating.
When familiar work gets harder, they concentrate more. Put in more time. Double-check decisions. Take on more themselves. Draw more heavily on the people around them. And often they continue to produce the expected result.
Which is precisely why the result can be misleading.
Eliz’s work on Capacity Signals focuses on the early indications that familiar work is requiring more time, effort, attention, recovery, or support.
Recognizing those changes provides useful information about the capacity actually available.
Then comes the more important question: What do you do with that information?
Eliz equips audiences to understand what affects their available capacity and to make practical choices about effort, recovery, and support, so they can protect the resources needed for sound decision-making, strategic thinking, health, and sustained performance.
Research That Shows Up in Real Life
Eliz’s work is grounded in research, but she is most interested in what that research looks like in the lives of people doing demanding work.
Sometimes the first indication that something has changed is surprisingly ordinary. Familiar information becomes harder to absorb. A routine task requires more concentration. Something that is usually easy suddenly takes more effort.
The task didn’t necessarily get harder.
The capacity available to do it changed.
Those are the moments Eliz pays attention to, because recognizing them sooner gives people more choices about how to respond.
A Few Things That Don't Fit in the Professional Bio
Eliz lives in Wisconsin with her husband, Clay. Their twin daughters, Grace and Callie, whose arrival coincided rather dramatically with the beginning of this story, are now adults.
She and Clay race sailboats on Lake Michigan on thier boat, Cattywampus. She serves as Race Chair for the Friday-night fleet, responsible for running fair races and keeping the fleet safe.
Eliz has celebrated more than 25 bonus birthdays since her heart attack. She’s planning on quite a few more.
What Eliz Brings to the Stage
Eliz combines research, relatable stories, humor, and audience interaction to make complex ideas easy to recognize in real life.
She has spoken to audiences including professionals at NASA, CVS Health, UPS, the American Heart Association, healthcare organizations, professional associations, and companies across the country. Her perspective has been featured on CNN, PBS, Lifetime, TNT, and other national media.
Her three keynote programs apply the same body of work to different challenges: recognizing changes in capacity, protecting decision quality during uncertainty, and addressing the physical burden of sustained pressure.
Eliz respects the people in the room enough not to tell them they simply need to work harder, care more, or find a better way to manage everything.
Most of them are already very good at getting things done.
She gives them a better way to recognize what it takes to get it done, along with practical ways to respond.
