001 Following the Old Sky
Hey Moth, for millions of years the brightest light at night was the sky, and you flew by it. Then we lit a lamp, and the same rule now spins you round it till dawn.
Which of our old rules is spinning us in circles?
Have you ever worked very hard and still gone nowhere?
It is late. A street lamp hums above a quiet road. Around it, a moth is flying in circles. Round and round. It will still be there at sunrise, tired and lost.
We always thought the moth loved the light. It does not.
What really happens
For millions of years, the brightest thing in the night was the sky itself: the moon, the stars and the glow above. So moths learned one simple rule: keep the brightest light above your back. That rule kept them flying straight and level.
Then we invented lamps. Now the brightest light is not above. It is beside them. The moth keeps its back to it, just as before, and the rule that once kept it straight now turns it in circles.
How we know: In 2024, scientists filmed insects around lights in high-speed 3D and found they tilt their backs toward the light instead of flying into it (Fabian and colleagues, Nature Communications, 2024).
The turn
The moth is not foolish. It is loyal to a rule that used to work.
We do the same. "Work harder." "Never say no." "Do it all yourself." These rules carried us here. But the world has moved the lamp.
Three takeaways
- A rule that worked yesterday can trap you today.
- Effort is not the same as progress. Circles are tiring too.
- When you feel stuck, check the rule, not your strength.
You were never lost. You were following the old sky.
The dogmas of the quiet past, are inadequate to the stormy present.
