📌“I Know What to Do… So Why Can’t I Do It?”

If you’ve ever said, “I know exactly what to do… so why can’t I just do it?”

You are not alone.

Welcome to being a human with a brain.

People think they’re missing motivation.

But most of the time? They’re missing strategy, structure, sustainability, and support.

And honestly… motivation is the least reliable ingredient in the entire change process.

I want to share with you what I’ve learned. 

We’re going to break this down gently, and truthfully. Ready?

The Myth of Motivation

Motivation is that exciting burst at the beginning: the Monday morning energy, the new-year spark, the “this time will be different” feeling.

But motivation burns hot and dies fast. It’s emotionally driven, and emotions fluctuate.

James Clear puts it bluntly in Atomic Habits:

“You do not rise to the level of your goals. You fall to the level of your systems.”

Craig Groeschel echoes the same truth in his habits teaching:

“Successful people do consistently what other people do occasionally.”

It’s not about motivation.

It’s about your systems.

Your discipline.

Your identity.

And - importantly- the way you start.

Most People Don’t Fail Because They’re Weak. They Fail Because They Start Too Big.

This is the part no one likes to admit.

We go from zero to perfection overnight:

Start running? Great, sign up for a 10k.

Start waking early? Perfect, let’s do 5am every day.

Start eating better? Awesome, no sugar ever again.

And then we burn out.

Not because we’re incapable…

But because we built an expectation instead of a habit.

(**Now I want to make it clear that for some people and their personalities, going hard and fast can actually work (take Andy with his 75 HARD challenge). However, for a lot of people - yours truly included! - that is not the case. And that’s ok!)

James Clear calls this the “2-minute rule”:

Make the habit so small you can’t fail.

Groeschel calls it “the power of pre-deciding”:

Make the choice once, not every morning.

The truth is: If the entry point is too high, your nervous system will reject it.

Not because you’re lazy. But because it’s unsustainable.

Sometimes You Can’t Start Alone, And That’s Not Weakness

We love the idea of being self-motivated, self-disciplined, self-starting, self-everything.

But some habits require scaffolding at first.

Take my cold-swimming journey.

There was no way I was going to start that alone, not in Tasmania’s winter, of all things.

So I found a friend. We went together, regularly, for almost a year.

That accountability mattered.

The shared dread, shared screaming, shared afterglow… it mattered.

And then I moved away.

But by then? Something incredible had happened.

The habit had roots. The endorphin reward was predictable. My identity had caught up.

Now I cold swim alone, happily.

Because I built it together first.

Some things you can do solo.

Some things you need a companion, a coach, a friend, or even a community to get moving.

Not forever. But at the beginning? Support is a strategy.

Small Habits Build Self-Trust

Another example: my morning walks.

For most of my life, I have not been a morning person.

Waking early felt like punishment.

But I wanted to start my mornings earlier instead of getting dragged out of bed by my screaming toddler, and walking in nature refreshes my soul.

So I wanted to start every morning… BUT I didn’t start with daily.

Or 5am. Or 10,000 steps. I started with two mornings a week. No rules about how far.

No expectations about intensity.

Just: “Show up.”

A quick walk. A quiet moment. A coffee.

A gentle nervous-system reset before the house wakes.

Now? I walk every morning, before my husband and kid start their day.

Not because I forced myself into discipline…

But because I grew into the identity of someone who keeps commitments to herself.

Some mornings it’s 2km.

Some mornings it’s 5km.

The distance never mattered. The follow-through did.

Here’s the truth no one seems to be telling us:

You don’t build a habit by proving you can do hard things.

You build a habit by proving you can do small things consistently.

That’s how self-trust is created.

Not by intensity, by reliability.

Why You “Know” What to Do But Still Don’t Do It

Because ‘the knowing’ isn’t the problem.

The execution system is.

You don’t need:

✖ more motivation

✖ more shame

✖ more pressure

✖ more “come on, just do it”

You DO need:

✔ a smaller starting point

✔ a sustainable structure

✔ a realistic pace

✔ a reason that matters to you

✔ and, sometimes, a person beside you

You’re not failing.

You’re trying to bulldoze your way into a new identity instead of easing yourself into it.

So… How Do You Actually Change?

Here’s the loving butt-kick part:

1. Stop trying to be perfect. Start trying to be consistent.

2 minutes > a perfect hour that never happens.

2. Choose habits that fit into your real life.

Not your ideal life.

Your actual life.

3. Start stupidly small.

If it feels “too easy,” you’re doing it right. Keep showing up.

4. Use support if you need it.

Accountability isn’t cheating. It’s wisdom.

5. Focus on identity, not outcome.

“I’m becoming the kind of person who…”

is far more powerful than “I need to finish this goal.”

AND... Give yourself grace if you fall. Get back up again and don't let one little thing de-rail your entire operation or send you into a tailspin pity party.

Habits are consistency NOT perfection.

You’re Not Broken. You’re Just Human.

You don’t need to “try harder.”

You need to start smaller, structure smarter, and support yourself better.

The gap between knowing and doing isn’t laziness.

It’s strategy and discipline.

And strategy is something you can learn. Discipline is something you can build.

One tiny, doable, consistent habit at a time.

See You on the Other Side
