The Reinventor's Mindset: Elephants, cages, and the freedom of constraints

Last week I stood in an operating theatre in Christchurch watching a hip arthroscopy up close.

I was visiting Mark Stewart, COO of Southern Cross Healthcare, to see how New Zealand's leading hospital network balances patient experience and operational efficiency. I'd squeezed the visit in between adviser conferences following the full launch of MLC Retirement Boost.

The surgical team moved like carpenters. Precise. Almost detached from the emotion of the situation. They put a patient into traction and dislocated their hip with the kind of bored efficiency that comes from doing it hundreds of times.

No fuss. No drama. No tolerance for bad attitudes - because in this environment, team disharmony isn't a culture problem. It's life or death.

The lead vest weighed heavy on my shoulders. The room was surprisingly warm. And I stood there thinking: this is the most constrained environment I've ever been in. Sterile. Hierarchical. Precise. Rehearsed.

And yet it produces extraordinary outcomes. Southern Cross runs a 90+ NPS - in healthcare. That's almost unheard of. It requires the entire patient experience to be run with military precision.

Debbie, the General Manager of Operations, walked us through how they do it. And the nurses? They have Fun Fridays where they wear colourful scrubs. Surprisingly meaningful. Surprisingly impactful for morale.

Because here's what Mark and his team understand:

"A day at work for you is a life event for your patient."

That line stayed with me. Because it's not just about healthcare. It's about showing up every day as if the work still matters - even when you've done it hundreds of times. Especially then.

That idea stuck with me as I flew home. Because it's exactly what this edition's guest has been living - across decades, industries, and identities.

Keep Treading Water with Nicholle Lindner

(Portfolio Executive and University Lecturer)

Nicholle Lindner has worked across CBA, NAB, Westpac, AT Kearney, Capgemini, Gartner and Unisys. She holds a Masters in AI and Expert Systems from UNSW - earned long before AI was fashionable - and has spent two decades teaching leaders how organisations actually change.

We first met on a panel at the Australian Consortium of Entrepreneurship Research Excellence, which is either a great place to find reinventors or a very long name for a very interesting room.

The hardest and the proudest

When I asked Nicholle to reflect on her proudest and hardest career moments, she gave me the same answer for both.

The GFC. She was at NAB. Her husband was at Westpac. Her role moved to Melbourne. And they were juggling a beautiful newborn.

Every week, she made the commute - dropping her daughter at NAB's daycare at 225 George St, ducking down in the lifts to breastfeed between meetings, then flying south into a world that was shedding jobs every minute.

"Getting through that, I'm extremely proud. It made me such a stronger person. It gave me the resilience."

She calls out her husband and her parents.

"It takes a village to get through these times."

But the weight was hers to carry. The hardest moment became the one she's proudest of - because difficulty was the teacher, and the resilience builder.

Going down and across to go up

At 40, Nicholle did something people talk about but few actually do. She left banking for consulting. Took a pay cut. Took a title cut. Changed careers.

"I had to go down and across to go up again. I took a pay cut, I took a title cut...to move across, because I had to learn a new trade effectively."

She'd spent her banking career watching technology reshape financial services and wanted to be building, not observing. The move cost her status and salary in the short term. It bought her a second career that took her to the forefront of technology consulting.

That's not a single reinvention. That's a pattern. The GFC didn't break her - it built the resilience that made the career pivot at 40 possible. And the pivot wasn't the destination. It was the next branch.

Reinventors and the open plains zoo

Nicholle's signature idea comes from watching large organisations try to innovate. They approach it like a traditional zoo: cage the creativity first, control it, make sure nothing escapes.

"If you put an elephant in a cage, it'll only grow to a certain size.

But if you let it roam, it will grow to its full size."

Her reframe: the open plains zoo. Room to roam with visible boundaries.

At NAB, she built the Ready ATM alliance - partnering with mutual banks through the Cusco network to expand the footprint. It was structurally novel for a bank accustomed to owning everything. It worked because the governance and compliance frameworks came first.

The constraints enabled the innovation:

"You've got to seek first to educate, then people will understand, and then they'll buy in."

Great grammar doesn't make a great writer

Nicholle now teaches at university, and she's watching AI reshape how students learn - or don't.

"Great grammar doesn't make a great writer.

You don't read a novel cover to cover because the grammar is perfect."

Her son, in his final year of law at UTS, still sits in the law library reading cases and holding books. Her daughter, starting PPE at Sydney, is learning the harder lesson: the university wants your point of view, not Claude's.

What Nicholle sees is students getting a filtered version of everything - efficient, competent, well-structured - but missing the friction that actually builds understanding. The group assignment everyone hates. The tutorial where someone says something and the pieces suddenly fit.

The messy, constrained process of thinking for yourself is the condition for developing taste.

There is no destination

When I asked Nicholle how she decides what needs to give - where to lighten the backpack, where to prune the tree - she didn't offer a system. She offered a disposition.

"Being comfortable with trade-offs is the best thing that I've become."

She holds the paradox of a portfolio career without trying to resolve it. Multiple identities. Kids and ageing parents. Breadth and depth. The sandwich generation pressures that every professional in their 40s and 50s recognises.

"A career will never love you back."

She said it simply, like something she'd known for a long time. And then she named the shift underneath it all.

Nicholle grew up in a culture that measured success by the ladder. Accolades. Prizes. End-of-year assemblies where the list gets read out and you're either on stage or you're not. As you get older, the prizes become monetary - title, status, public recognition.

A very Western, very Anglo-Saxon idea of what winning looks like. Somewhere along the way, that definition broke.

"The world is full of very, very unhappy people who are highly successful. My definition of success has changed from that very Western idea - that success is a ladder, that it doesn't matter how hard and long the struggle because the prize at the end is what's important - to more of an Eastern philosophy, which is it's the journey, not the destination."

It's the people you've pulled up behind you. The freedom to pursue what you actually love. The sign of a truly successful person, Nicholle says, is having the time to follow your passions - family, friends, study, cultural pursuits.

Not the accolade. The agency.

That's the Keep Treading Water framework. There is no destination. There's only the next branch, the next trade-off, the next chapter.

The portfolio career isn't a strategy. It's a philosophy - that the tree never stops growing.

And the hardest moments? They're not obstacles on the way to success.

They are a gift. A teacher.
