Systemise or stay stuck.

Being busy isn’t building.

Back in 2018, I was slammed.

Running MailNinja. Hiring staff. Delivering campaigns.
60-hour weeks. Felt like growth.

It wasn’t.

Truth?
Busy ≠ growth.
Revenue ≠ freedom.

Real growth came when I started systemising:
→ My onboarding
→ My offers
→ My content

That’s when the flywheel clicked.
When I had time and scale.

If you’re always busy, you’re likely building a job.

Systemise or stay stuck.

The “2-in-1” Loop

The “2-in-1” Loop
(from the GrowthKit Vault)

Most founders treat email and content as separate machines.

But if you link them up → your growth goes exponential.

I call it the “2-in-1 Loop”:

→ Write a weekly newsletter
→ Post that content on LinkedIn
→ Add a CTA to join your list
→ Send the next edition to those new subs
→ Repeat

The loop builds momentum.
Every post grows your list.
Every email grows your LinkedIn.

It’s how I added 50+ subs per day.

Use one asset to power both.

♻️ Loop it or lose it.

More content → more growth

Back when I was running MailNinja, I thought I needed 100 fresh ideas a month to grow.

BS.

What I actually needed?

One idea.
And a system.

That’s how I created the Content Waterfall System™—the same system I still use today to grow GrowthKit without burning out.

Here’s how it works:

💡 Step 1: Capture one powerful idea a week
Think: a belief, a hot take, a client mistake, a lesson from your past.
Something you’d rant about over coffee.

🎯 Step 2: Repurpose it across the flywheel
→ A LinkedIn post
→ A story in your newsletter
→ A quick Loom vid
→ A CTA to your lead magnet
→ A tweet
→ A post in your Skool community

One idea → 5+ assets.
No content calendar. Just clarity.

🔁 Step 3: Recycle what works
Great post? Repost it in 90 days.
Great email? Turn it into a post.
Run the system again next week.

This is how I show up daily.
Not because I hustle harder—
But because I systemised how I create.

More content ≠ more growth.
Better systems do.
