Content Waterfall System

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.
