No. 590 / When green meant stop

Until 1925 in NYC, people were used to driving through red stop lights but stopping at green. It was the norm and people were used to it. Until that changed and red became the international color that meant ‘stop.’

That’s the power of an idea. It started when people put their heads together and realized that our brains respond differently to various colors. Then they approached some influential people with viable solutions and, before you knew it, green meant something different than it did a few years earlier.

Ideas are the the lifeblood of organizations and societies alike. Ideas that spread can make or break your current system. And ideas become greater when others build on them.
