There are moments when time stops being abstract.

For me, that happened the day my life split into before diagnosis and everything after. The future stopped behaving like an open-ended idea and started acting more like a set of probabilities. Weeks mattered. Numbers mattered. Median life expectancy stopped being something that applied to other people.

In a practical sense, I also retired early.

  • Not by choice.
  • Not by financial independence.
  • But by diagnosis.

Cancer didn’t just interrupt my health — it quietly removed the scaffolding that had held my days together: work rhythms, long-range plans, the assumption that tomorrow would look broadly like today. In that sense, cancer forced a kind of early retirement that no FIRE (Financial Independence Retire Early) spreadsheet prepares you for.

And it left me with a question I didn’t expect to be so central:

What am I living for, now that everything familiar has been stripped away?

The Quiet Risk of Losing Purpose

I’ve been watching a lot of content lately about early retirement — not because I aspired to it, but because I recognize the shape of the problem.

People retire early, financially secure, and something unexpected happens. Motivation fades. Days blur. Identity erodes. Not immediately, but subtly. Slowly.

The theme that keeps surfacing is not boredom. It’s not money.
It’s the loss of purpose.

That insight landed uncomfortably close to home.

Because cancer patients, especially those in long-term treatment, experience many of the same conditions as early retirees — but under far harsher circumstances:

  • Structure disappears.
  • Identity is disrupted.
  • Long-term certainty collapses.
  • The future becomes conditional.

Except instead of freedom, there is fear.

A Hypothesis I Can’t Shake

  • This is not a scientific claim.
  • It’s an observation. A working theory.

I’ve begun to suspect that fighting cancer without an underlying purpose may be one of the reasons some patients don’t last as long as they might have otherwise.

  • Not because purpose cures disease.
  • Not because optimism overrides biology.

But because purpose changes how someone shows up for the fight.

  • It affects whether you endure treatment rather than merely survive it.
  • Whether you maintain routines when motivation evaporates.
  • Whether you take ownership of your body, your data, your days.

I’ve read that some healthy retirees die sooner than expected after leaving work — not because retirement is deadly, but because the sudden absence of meaning accelerates decline.

If that’s true for healthy people, then what does it mean for someone like me — someone forced into early retirement by cancer?

My working belief is this:

If a healthy retiree can decline quickly without purpose, then a cancer patient who loses theirs may have even slimmer odds of breaking beyond the median.

Treatment Is a Full-Time Job — Without the Title

During treatment, time becomes granular.

You start measuring life in cycles, infusions, lab results, and symptoms. You learn to read your body the way others read performance metrics. You settle into rhythms that are invisible to the outside world but all-consuming inside it.

I’ve written before about waiting for proof before taking the next step, and about watching numbers slow down on the eve of an infusion. Those moments taught me that passivity is dangerous — not medically, but psychologically.

When you stop participating in your own life, even briefly, things slip.

Purpose became the counterweight.

Purpose Is Not Motivation

This is important.

  • Purpose is not enthusiasm.
  • It’s not positivity.
  • It doesn’t require optimism.

Purpose is structure plus intention over time.

For me, that has looked like a structured meal plan that supports resilience rather than indulgence.

  • Daily movement, even when energy is low.
  • Writing — not to inspire, but to document.
  • Treating treatment itself as a discipline.

These are not heroic acts. They are small, repeatable commitments. But together, they create something larger: a reason to persist with care.

  • I’m not just enduring treatment.
  • I’m participating in it.

Living Beyond the Median

Median life expectancy is a statistical midpoint, not a sentence. Half the people fall on one side. Half fall on the other.

I don’t know which side I’ll end up on.

But I do know this: I refuse to let the absence of purpose be the reason I don’t get there.

  • Purpose doesn’t change the diagnosis.
  • But it changes the experience of living with it.
  • It keeps time from collapsing into waiting.
  • It keeps days from becoming interchangeable.
  • It keeps me engaged in my own survival.

This Is Not About Beating Cancer

This is about showing up fully while living with it.

If I live beyond the median, I want it to be because I treated my life as something still worth building — not because I waited passively for outcomes.

If I don’t, I want to know that I fought with intention, structure, and agency.

  • Purpose doesn’t guarantee survival.
  • But without it, I believe the odds quietly worsen.

And for now, that belief is enough to keep me moving.
