Tiny Experiments

High performers don’t usually struggle because they lack discipline.

They struggle because they treat change like a verdict.

Last month I wrote about why most resolutions wobble. Why it’s rarely a willpower problem. Why motivation alone isn’t a reliable foundation for change.

But even when we shrink the habit, something else often gets in the way.

We measure progress in outcomes:

Did it work? Did it pay off? Am I further ahead? Success or failure.

And when the answer isn’t immediately obvious, we quietly decide we’ve failed.

That all-or-nothing thinking is the actual problem.

Not ambition. Not capability. The measurement system.

And this is where tiny experiments change everything.

What is a tiny experiment?

A few years ago, a friend told me about something she had done.

For 500 days, she ran a personal experiment.

Every single day she tried something new. Sometimes it was big. A bold move. A difficult conversation. A decision that stretched her. Other days it was small. Taking a different route home. Trying something she would normally dismiss. Responding differently to a familiar trigger.

Five hundred deliberate interruptions to autopilot.

At its simplest, a tiny experiment is just that. A deliberate test. You choose one small action and run it for a defined period of time to see what shifts.

It doesn’t have to be 500 days. It could be a week. Ten working days. A fortnight. The point isn’t the scale. It’s the consistency and the awareness.

It’s now a huge part of how she tells her story. That period didn’t just change what she did. It changed what felt possible. By the end of those 500 days, she left her job and set up her own business in resilience and leadership development.

Not because of one lightning bolt moment.

Because she had built evidence, day by day, that she could adapt.

That’s the mechanism.

Repeated, low-risk experimentation builds identity.

I’ve used this approach myself during seasons that felt chaotic. Not reinventing everything. Just running small, deliberate tests until something stuck.

Sometimes my “experiment” is nothing more than leaving my yoga mat rolled out, ready for the ten unexpected minutes that would otherwise disappear into emails or doom scrolling.

What the research tells us

(and yes, there is science behind this)

Repetition changes the brain

Habits strengthen through frequency. The brain reinforces neural pathways through repetition, not intensity. When a behaviour is small enough to repeat, it gradually requires less effort.

You don’t need it to be impressive. You need it to happen again tomorrow.

That’s how it sticks.

Clarity increases follow-through

There’s strong evidence behind something called implementation intentions. In simple terms, when you decide in advance exactly what you’re going to do and for how long, you’re far more likely to follow through with it.

“I’ll try to read more” is vague.

“I will read for 15 minutes after dinner, Monday to Friday, for the next two weeks” gives your brain something concrete to act on.

Specific reduces friction.

And friction is often what stops us, not motivation.

Psychological flexibility builds resilience

This is the part that matters most.

When you frame behaviour as an experiment, it becomes information.

Not proof that you’re inconsistent. Not evidence that you’ve failed.

Psychological flexibility, the ability to adjust without collapsing into self-criticism, is consistently linked to wellbeing and resilience.

If every attempt feels like a referendum on who you are, you eventually stop trying.

If it’s an experiment, you stay engaged.

From goals to pacts

One idea that really resonated with me was the concept of a pact.

Not a goal. A pact.

A pact shifts the focus from outcomes to outputs.

Not “be more confident in meetings.” Preparing one clear point before every team call this month.

Not “get promoted.” Spending 20 minutes developing one relevant skill each week.

Not “be less stressed.” Taking a 5-minute reset before your first meeting.

Outcomes are seductive. They’re visible. They feel validating.

Outputs are controllable.

A strong pact is:

Purposeful Actionable Doable with the resources you already have

And it’s tracked simply.

Did you do it? Yes or no.

No spiralling. No performance narrative. Just information.

The emphasis is on doing over planning.

Reps over intention.

Work with your energy, not against it

We also don’t have equal capacity all day.

Instead of demanding perfection across twelve hours, notice your “magic windows”. The natural pockets of focus, clarity or space.

A quiet commute. Twenty minutes before a meeting. An unexpected gap in the afternoon.

Use those windows intentionally.

Research on energy cycles and performance consistently shows we perform better when we work with natural fluctuations rather than forcing constant output.

Sustainable high performance is alignment, not intensity.

Why this matters

Most ambitious people don’t struggle with starting. They struggle with sustaining.

We know how to set goals. What’s harder is keeping something going once the novelty fades and life gets busy.

When everything feels like a performance review, even your own habits, growth becomes exhausting. Every wobble feels personal. Every missed day feels like evidence that you’re not disciplined enough.

Tiny experiments change that.

They don’t lower the standard. They change how you measure progress. Instead of asking, “Did this work?” you ask, “What did I learn?”

That shift makes it easier to stay consistent during busy seasons, high-pressure projects, or weeks where your energy isn’t perfect.

Sustainable high performance isn’t built in dramatic moments.

It’s built on ordinary days.

So, what can we actually do?

If this is resonating, I’ve shared the rest of this piece over on Substack. You can finish reading it here.

Want to work together?

I work with individuals who are navigating pressure, change, or a sense that something needs to shift. That might look like a career transition, stepping into a bigger role, or finding your feet again after time away, including returning to work after having a baby.

My work is grounded in coaching, psychology, and a strong belief that performance and wellbeing shouldn’t be in competition with each other. I keep my coaching practice intentionally small, so I only open a limited number of spaces at any one time. You can book a free intro call here.
