Not for a day.

Not for a week.

But when it’s cold, wet, you’re tired, and nobody would blame you for skipping it.

Because that’s when discipline actually matters.

At the end of May, I ran a 10km race.

To be honest, it wasn’t great.

I felt sluggish, heavy, and underprepared. It was probably my slowest 10km race for a long time, and as I crossed the finish line, I knew I hadn’t turned up in the condition I was capable of.

Like most people, I had plenty of reasons.

Work was busy.

Life got in the way.

The weather wasn’t ideal.

But reasons and excuses don’t improve performance.

Action does.

So I set myself a challenge.

Run every day throughout June.

Nothing extreme.

Just a minimum of 2 miles per day and gradually increase the mileage as the month progressed.

The first week was tough.

Every run felt like an effort.

I questioned why I had started.

But around Day 11, things began to change.

My pace improved.

My stamina improved.

And perhaps most importantly, getting out of the door became easier.

Not because I suddenly felt more motivated.

Because repetition was creating momentum.

Halfway through the month, these are my biggest takeaways:

• The first week is always the hardest.
• Repetition drives improvement.
• A goal creates purpose.
• Purpose sustains motivation.
• Discipline eventually becomes habit.

The interesting thing is that this doesn’t just apply to running.

It’s exactly the same in our careers.

Particularly in manufacturing and operational leadership.

The biggest improvements rarely come from dramatic changes.

They come from consistently doing the fundamentals well.

Having the difficult conversation.

Reviewing the data.

Coaching your team.

Following the process.

Solving the root cause instead of applying another quick fix.

The things that feel repetitive and sometimes boring are often the things that make the biggest difference.

Performance is usually the outcome of what you repeatedly do, not what you occasionally do.

So my question is:

How could you test your discipline over the next 30 days?
