What you're seeing
A community of people. One person starts inspiring others (gold glow). When an inspired person is near an uninspired person, the encouragement may spread.
How to read the graph
Gray dots haven't been reached yet. Glowing gold dots are actively inspiring those around them. Faded dots were previously inspired but the active spark has passed — though the impact remains.
The key lesson
Inspiration spreads through the exact same math as disease. The same dynamics that make pandemics terrifying make mentorship, teaching, and kindness powerful. Contagion is neutral — what matters is what you carry.
