I was recently thinking about how some things circulate, and some things don’t.

Our blood circulates. That’s an easy one to recognize. Something goes into the system, and it gets distributed.

Then I thought of things that don’t circulate. Like rivers. Something goes into the system, and it flushes downstream. Gone.

Except, of course, rivers do circulate. Water molecules do, anyhow. Earth’s water cycle just has a slower path, through evaporation and precipitation.

So when we’re impatient about an idea spreading... When we think our work isn’t circulating... it might be true. But it’s possible that the cycle is just longer than we had anticipated.
