Watching tea leaves uncurl in hot water isn’t particularly interesting. The progress takes on its own pace, and there’s no real outcome in waiting.
Likewise, waiting for culture to change takes a long time. The one thing that speeds up the process are trends, and trends come in waves which speeds up the uncurling, expanding, and brewing process. And, they don’t last for a long time.
We need lots of tea and hot water to help the culture of environmental sustainability uncurl and become stained into our lifestyles.
