Hey 👋🏼 - I’m John... and I absolutely LOVE business...
..And before helping other businesses scale, I actually scaled one. For the past few years, I have been the CEO of Investment Mastery, Europe's most reputable investing education company. The "success story" here is that we revived the company from almost dying in 2020. 🥴

Against all odds, we scaled to over $22.3m in sales over four years, servicing over 7,000 clients in over 25 countries. This incredible journey taught me something: simple, effective systems are the keys to business success. Follow me for daily content on business systemisation, sales, marketing, culture, management, and leadership. All everlasting skills I have acquired throughout my journey in business.

You had an idea. Then you made it real. That is magic. ✨

That is easy to forget when you are deep in the day-to-day of running the business.

But most people never do that.

They never take the thought.

Build the offer.
Find the client.
Deliver the work.
Create the team.
Carry the risk.

YOU DID. That matters.

You are not just running a business.

You created something from nothing.

Now the next job is to build it properly, systemise it, and make it strong enough to scale.

Stop writing processes nobody uses.

Your team do not need a 12-page SOP.

They need a simple playbook that tells them:

→ When does this start?
→ What happens next?
→ What number tells us it worked?

That is what makes a system useful.

Clear trigger.
Clear action.
Clear measure.

If your team still need you to remember it for them...

It is not a system yet.

Your business does not have 50 problems.

It probably has 5 friction points that keep repeating.

The same questions.
The same decisions.
The same fires.
The same things landing back on your desk.

That is where you start if you want to systemise your business.

Not with another hire.
Not with another tool.
Not with a massive manual nobody reads.

Map the work.
Find the friction.
Fix the right thing.

That is how you scale your business without adding more chaos.

The reminder we all need sometimes

10/08/2026

Hiring more people will not fix a business that still runs from your memory.

It usually makes the bottleneck worse.

Because now the team need you to explain how the work should be done.

Again. And again. And again.

Before you hire, you need:

➡️ The work mapped
➡️ The playbook written
➡️ The numbers tracked
➡️ The system in place

The right people can only do great work when the way of working is clear.

That is how you scale your business without adding more confusion.

Money is just a tool.

But too many business owners let it define how they feel.

One look at the bank account and suddenly the whole day changes.

But the number is not there to hurt you.

It is there to show you what needs action.

➡️ Look at it.
➡️ Understand it.
➡️ Make a plan.
➡️ Move forward.

You do not need every number to look perfect.

You just need to stop avoiding the ones that do not.

That is how you lead the business properly.

You don’t want to be rich so you can buy fancy stuff.

You want to be rich so you can travel the world with your loved ones.

So you can sit with a coffee and enjoy slow mornings.

So you can step away from your business and know it works without you.

So you never miss a single family moment.

That is being rich, and it has nothing to do with buying things to impress strangers.

No government is coming to save your business.

❌ Not Labour.
❌ Not Conservative.
❌ Not Reform.
❌ No one.

And that is not a political point. It is a business point.

The UK might not feel easy for business owners right now.

But waiting for things to get easier will not move the business forward.

➡️ You still have to adapt.
➡️ You still have to stay agile.
➡️ You still have to make better decisions with what is in front of you.

Because there is no perfect place to build a business.

There is only the environment you are in...

And how well you respond to it.
