Psychology of Health Pt II: Perfectionism

In the first article in this series we discussed a simple framework borrowed from Morgan Housel’s work in The Psychology of Money:

Happiness = Expectations – Reality

This equation applies to almost every area of life, including health.

When expectations are reasonable, people tend to feel satisfied with progress. When expectations are unrealistic, even objectively good outcomes feel like failure.

One of the biggest drivers of unrealistic expectations in modern health culture is the rise of optimization and perfectionism.

Over the past several decades there has been a major shift toward wellness culture. Some of this is positive. People are exercising more, thinking about nutrition, and taking ownership of their health.

But there has also been a shift toward something more subtle: the idea that we should be optimizing everything all the time.

Terms like biohacking, health optimization, and performance culture have become increasingly common. Social media amplifies this by creating constant comparison. It appears as if everyone else has perfect discipline, perfect health routines, perfect finances, and perfect lives.

In reality, that person almost never exists.

I’ve met many people who are excellent in certain areas of life—people who have strong systems for health, relationships, finances, or personal growth. But I have never met someone who has mastered everything.

Life is a series of trade-offs.

The Missing Question: What Is Enough?

One of the most important questions people rarely ask themselves is:

What does “enough” look like?

If “enough” is never defined, expectations become endless. People begin expecting to have elite fitness, perfect nutrition, ideal sleep, a thriving career, strong finances, a great marriage, and perfect parenting—all at the same time.

And preferably by next month.

When expectations become that high, even good progress feels disappointing.

The Illusion of Speed

Another issue is that modern culture has distorted our sense of time.

We live in a world of Amazon Prime, overnight shipping, and instant information. As a result, many people expect transformation to happen quickly.

But real progress in health almost never works that way.

Most meaningful improvements happen slowly. Often they take years or decades, not weeks or months.

There are cultures that understand this better than we do. Some long-standing family businesses in Japan operate on 100-year time horizons, making decisions based on what benefits the organization over generations.

Contrast that with modern American systems that often focus on quarterly performance. When everything is evaluated every three months, short-term results are prioritized over long-term stability.

Health works the same way. If someone expects dramatic improvement in 30 days, they will often abandon the process long before meaningful change occurs.

The Perfectionism Trap

Ironically, one of the most common outcomes of perfectionism is that people do nothing.

When someone believes they must do everything perfectly—perfect diet, perfect workout routine, perfect sleep, perfect supplements—the task becomes overwhelming.

The result is paralysis by analysis.

Instead of making progress, people stall because they believe their effort won’t be good enough.

The solution is not complicated:

Decide what “good enough” looks like.
Focus on one thing at a time.
Give yourself enough time for progress to occur.

There Are No Health Hacks

Another modern illusion is the idea that health can be hacked.

Between wellness influencers and trends like the Financial Independence Retire Early (FIRE) movement, many people now expect rapid transformation—get rich fast, get healthy fast, optimize everything quickly.

But almost everything meaningful in life follows the same rule:

Progressive overload.

Small improvements, repeated consistently over long periods of time.

And even then, life happens.

There will be seasons where things regress. People get injured. Kids are born. Work becomes overwhelming. Sleep gets disrupted.

Because of this, pursuing perfect health during every phase of life is unrealistic.

Reality Is Messy

In Awareness, Anthony de Mello wrote that perfectionism reflects a disconnection from reality.

Perfection requires imagining a world that doesn’t exist.

One of the goals of maturity is learning to see reality clearly: people make mistakes, progress is uneven, and improvement is always incomplete.

This idea is captured beautifully in the book Chop Wood, Carry Water. Life is less about dramatic breakthroughs and more about consistent repetition.

Plan. Do. Review. Repeat.

Run the experiment. Adjust. Keep moving.

Grace Matters

Part of the modern pressure toward perfection comes from public criticism. In an era where mistakes are amplified online, people begin to believe that perfection is required.

But perfection isn’t human.

I’ve never met a perfect parent. I’ve never met a perfect spouse. I’ve never met a perfect child.

And after years in medicine, I’m still waiting for the perfect patient to walk through the door.

In reality, most people are far too hard on themselves.

What most of us need is not more pressure, but more grace—both for ourselves and for the people around us.

Because if you hold everyone to a perfect standard, eventually everyone will disappoint you.

Progress Is Enough

A useful reframing is this: Many people who describe themselves as perfectionists are simply high-drive individuals who value progress.

But labeling yourself a perfectionist often reinforces a mindset that guarantees dissatisfaction.

Instead, accept something simpler and more realistic:

You are human.

You make mistakes.

You learn.

You keep going.

Sometimes decisions have to be made with 70–90% certainty, not 100%. Sometimes the odds of success are unclear. Sometimes any change is better than continuing down a path that clearly isn’t working.

If a couple fights every day and never goes on dates, the probability of a healthy marriage is close to zero. Almost any change to the system improves the outcome.

The same principle applies to health.

If you follow any structured plan, you are already ahead of doing nothing.

And even people who simply show up consistently often improve over time because they absorb enough information to eventually figure things out.

The Real Goal

The goal isn’t perfection.

The goal is simple:

Just try to do a little better over time.

Life is a long experiment. Once you accept that no one is perfect—not you, not your spouse, not your children, not your patients—the pressure eases.

And the process becomes much more sustainable.

Keep showing up.

Keep learning.

Keep improving.

That’s enough.

Three Key Takeaways

Optimization culture often creates unrealistic expectations, which leads people to feel like they are failing even when they are making progress.
Health improvements happen slowly, usually over years rather than weeks or months.
Consistency beats perfection. Showing up regularly matters far more than having the perfect plan.
