🚀 Grow Your Substack with Heart: the Kindness Challenge 🚀
Unlock Viral Growth: Weekly Notes to Elevate Your Substack
We're taking the Substack Boost one step further—a push to expand both our community and our well-being.
Why stop at growing our newsletters when our health can benefit as well?
The Kindness Challenge
This week, we launch the Kindness Challenge.
And it’s not just a feel-good idea—it’s backed by science.
🔬 Researchers conducted a large-scale randomized controlled trial in the U.S., Australia, and the U.K. with 4,500 participants.
Half were assigned to perform small acts of kindness for their neighbors, while the other half formed a control group.
The Results?
Kindness significantly:
Reduced loneliness
Reduced stress
Reduced conflicts
Your Challenge
Each day this week, do one small act of kindness.
A genuine compliment, helping someone out, listening with full attention, or simply offering a warm smile.
Small actions, big impact.
How to Participate
1️⃣ Write a short kindness note in your Substack.
2️⃣ Copy the note in the comments and drop the link so others can read it, connect, and get inspired.
3️⃣ Connect with at least 3 people—genuinely. Read their notes, reply with something meaningful, and build real relationships. Let’s exchange ideas and support fellow newsletters by commenting, liking, and restacking.
This is NOT a "drop your link and run" challenge.
Growth happens through meaningful connection
My Example of Today’s Note
Hold the door.
Let someone go first in line.
Say “thank you” like you mean it.
You never know.
The person rushing past you might be fighting battles you can’t see.
The cashier who seems distracted might be grieving someone they love.
The stranger who barely looks up might be carrying the weight of the world.
A small act of kindness could be the only light in their day.
Be that light.

Drop your note with the link in the comments and connect with at least 3 others. Ask questions, share thoughts, and make it meaningful. ❤️

Kindness Isn’t Soft—It’s Strong
Kindness isn’t about pleasing people. It’s not about being agreeable. It’s the quiet force that holds boundaries, stands firm in truth, and chooses presence over approval.
✨ It strengthens, not weakens.
✨ It creates space, not silence.
✨ It reshapes self-respect.
Real kindness isn’t passive—it’s power, steady and unwavering.
"Tenderness and kindness are not signs of weakness and despair, but manifestations of strength and resolution."
— Kahlil Gibran
