Hey Reader!

This week, I want to talk about the difference between something being complicated versus complex.

Might sound like semantics, but mindset is so important when dealing with an injury. Especially the chronic ones.

I've seen having the right framework make or break whether people are able to weather the ups and downs of any rehab journey.

So what am I even talking about?!?

Sending a person to the moon? That’s complicated.

​
There are a ton of moving parts. Every step has to fit together perfectly, and you need a crazy amount of knowledge to make it happen.

But here's the thing: it’s still predictable.

If you tweak a variable, like adjusting the trajectory by 10° or just add a little more fuel, you can forecast the exact outcome.

NASA can predict to the literally the second when and where someone will reach orbit, dock at the space station, and touchdown onto the moon.

Now, raising kids? That’s complex.

​
Sure, on paper, it seems pretty simple: feed them, keep them safe, clean up the messes.

But anyone who’s been around kids knows it’s anything but predictable.

You can do everything "right" with two kids in the same house, raised the same way, and still end up with two completely different humans.

Different personalities, different values, different everything.

Why?

Because there are way too many variables that interact in unpredictable ways. Lived experiences, environment, genetics, emotions, and about a hundred other things you can’t fully control or measure mix together to create something that isn't simply the sum of its parts.

Rehabbing an injury falls into this category.

It’s complex, not complicated.

The 30k view of the process sounds simple, right?

1. Calm the symptoms down
2. Restore mobility and range of motion
3. Build back strength and capacity
4. Return to sport or training gradually

Straightforward.

But if you've ever dealt with a nagging or chronic injury, you know it rarely plays out that cleanly or linearly.

That’s because we’re dealing with a complex system: your body, your lifestyle, your brain.

Things like:

• Sleep
• Nutrition
• Stress levels
• Training history
• Motivation
• Fear of re-injury
• External pressures (like a race date or team tryouts)
• Internal expectations (“I should be better by now”)

All of these factors interact in ways we can’t fully predict.

They influence how fast (or slow) you recover, whether you hit setbacks, and how confident you feel along the way.

So, just like raising a kid, rehab can look straightforward on paper. but real life doesn’t work like that.

And that’s okay.

The goal isn’t to control every variable.

It’s to respond to them.

That’s where coaching, communication, and flexible problem-solving skills come into play.

Rehab is a living process.

It’s not about perfection.

It's about having clear goals and clear next steps while navigate the gray areas.
