rule of 0.3 percent

We’ve got around 10,000 kilometers of atmosphere.
The Earth’s radius? Over 6,000 kilometers. That’s a lot of rock and sky.

But here’s the twist—what about life?

Life only shows up in this tiny slice of space:
Roughly 3 kilometers below the surface, and up to 50 kilometers above it.

That means, out of a full 16,000 kilometers from Earth’s core to the edge of the atmosphere,
only 53 kilometers are home to anything alive.

Do the math—
That’s just 0.3 percent.
Yes, zero point three percent. Not three. Not thirty.

0.003!

All that mass and space… just to support this thin strip shelter where life can happen.

So what’s the takeaway?

To me, it says something deserving of thinking:
If even 0.3 percent of your life shines with real goodness—
and the rest simply holds it up, supports it—
you’ve done something big. You’ve done your part!

Sounds tiny, right?
In a 75-year life, that’s about three months.

But, here’s the kicker—
I doubt that more than 0.3 percent of people ever achieve even that.
