Life Begins at 40? Why Midlife Could Be the Most Fulfilling Chapter Yet
Key takeaways
The saying “life begins at 40” is comforting, but today’s reality is more nuanced.
For many Australians, midlife marks a true turning point, a phase where priorities shift from external achievements to inner fulfilment and deeper purpose.
This stage is often misunderstood as a period of decline, but it can actually be the most enriching part of life.
Midlife isn’t about crisis; it’s about opportunity. It’s a chance to stop chasing society’s milestones and start defining success on your own terms.
No matter your age, if you’re asking the big questions, you’re right on time.
You’ve probably heard the old saying, “Life begins at 40.”
It’s one of those phrases that sounds comforting, but does it actually reflect reality?
Is midlife really a time of renewal, or is it just a feel-good mantra designed to soften the blow of grey hairs and creaky joints?
As Simon Kuestenmacher and I recently discussed in our Demographics Decoded podcast, midlife is far from just a number on a birthday cake.
For many Australians, it marks a unique turning point, a time when life’s purpose deepens, priorities shift, and (believe it or not) happiness can actually climb to new heights.
Let’s look at why midlife might just be the start of something far greater than the first 40 years and why today’s generation is redefining what this stage of life looks like.

The U-Curve of happiness: a map for midlife
There’s compelling evidence from around the world for what researchers call the U-curve of happiness.
The idea is simple: we tend to start life feeling upbeat and hopeful.
But as we take on more responsibilities, careers, kids, mortgages, and ageing parents, happiness levels often decline.
This dip usually bottoms out somewhere in midlife, and then begins to rise again as we age.
Now it’s not hard to see why.
The early decades of adult life are often spent striving for career success, financial security, and family stability.
We’re busy proving ourselves: to parents, bosses, society, and often to ourselves.
But once we’ve ticked off those major life milestones, many of us start to ask: What now?
And that’s the sweet spot.
As Simon put it, it’s at this point, once we’ve survived the so-called “dark night of the soul”, that happiness starts to rebound.
We move beyond chasing the next promotion or the bigger house, and instead begin to find joy in simpler, more meaningful things.
Why life begins at 45 – not 40
While Carl Jung’s famous quote, “Life really begins at 40. Until then, you’re just doing research,” has stood the test of time, Simon highlighted that for today’s Australians, life’s second chapter often starts closer to 45.
Why? Millennials, now entering their midlife, have done things differently.
Compared to previous generations:
- They’ve delayed milestones: later career starts due to longer periods in higher education. First-time motherhood now often occurs in the mid-30s rather than the mid-20s. First home ownership has been pushed back by soaring property prices.
- They’re juggling more at once: Many are still paying off large mortgages, supporting teenage children, and beginning to care for ageing parents, all at the same time.
So it’s not the age itself that signals midlife’s shift.
It’s the stage of life, that point when the identity we’ve built starts to feel a little hollow, and we begin to seek deeper meaning beyond external achievements.
Individuation: the journey beneath the mask
Midlife offers the opportunity for what Jung called individuation, the process of discovering your true self, hidden beneath the roles you’ve played.
In the first half of our lives, we wear a “persona”, the socially acceptable mask that helps us navigate the world, win approval, and achieve success.
It serves us well.
But at some point, many of us start to question: Is this all there is?
Simon eloquently described this process of turning inwards, confronting the parts of ourselves we’ve hidden away or ignored.
It’s about facing our “shadow”, those uncomfortable truths, regrets, or less flattering aspects of our personality.
This isn’t easy work.
It’s far simpler to keep chasing external validation than to look in the mirror and confront what we’d rather not see.
But those who do the work often find midlife becomes a gateway to greater peace, authenticity, and fulfilment.
Why midlife sparks change: new businesses, new paths, new priorities
Interestingly, this inner shift often coincides with outward changes.
- Entrepreneurship booms: Contrary to the popular image of young tech founders, the average age of first-time business owners is mid-40s. Many feel the pull to do something more meaningful, something that reflects who they really are, not just who the world expects them to be.
- Rethinking relationships: It’s no coincidence that divorce rates spike in midlife. When people take stock of their lives, they sometimes realise their partnerships no longer serve them, or that they’ve grown in different directions.
- Financial awakening: Many Australians in their 40s and 50s finally feel on more stable ground financially, or at least they start to think seriously about their long-term future. At Metropole, we see this all the time: clients recognising that super alone won’t secure their retirement, and seeking to build a more robust financial foundation through property or other investments.
Yet, Simon made an important point: financial pressures today can actually delay this inward journey.
With bigger mortgages and more extended financial responsibilities, many Australians simply don’t have the time or mental space to embark on deep self-reflection, or they postpone it until retirement or a health scare forces their hand.
What if an entire generation starts asking bigger questions?
Here’s a fascinating idea: as millennials, now the largest generation, move into midlife in record numbers, could we see a societal shift?
Simon speculated on what might happen if more of us entered this stage of deeper reflection at the same time.
Could we see political narratives move away from individual gain and towards collective wellbeing?
Could businesses and institutions begin to cater more to people seeking meaning over materialism?
It’s a big, speculative question, but one worth pondering as Australia’s population ages.
It’s never too late to begin again
For those who feel like they’ve missed their chance, maybe you’re in your 50s, 60s, or beyond, here’s the good news: the second half of life isn’t tied to a number.
You can begin this inward journey at any stage.
Sometimes, it’s triggered by life events: a health scare, the loss of a loved one, or the transition into retirement.
These moments strip away the external structures we’ve built our identities around and force us to consider what really matters.
The process of individuation isn’t easy.
It takes courage to face your shadow.
But those who do often find midlife and beyond become the richest, most satisfying years of all.
Final thoughts
Midlife is often misunderstood.
It’s not just a crisis; it’s an opportunity.
A chance to reframe what success and happiness really mean.
To move beyond chasing milestones and instead, to build a life rooted in authenticity and purpose.
So, whether you’re 40, 45, 55, or 65, if you find yourself at that crossroads, asking the big questions, embrace it.
Because in many ways, that’s when life truly begins.
