So we're talking about purposes.
And purposes are what a system is trying to accomplish.
They have potential to shape system behavior more than the elements, stocks,
flows, or even feedback loops.
So you talk about falling balls in Baltimore and happy.
>> Bhutanese.
>> [LAUGH] Bhutanese?
Can you explain that?
>> Yeah, so Bhutanese are people from Bhutan.
So that's the sustainability example is way back in the,
I think it was the 70's, Bhutan got a new king, who was 17 at the time.
And he said that they're going to make,
instead of measuring gross national product, they're going to measure gross
national happiness, and they actually measured both.
So they basically changed kind of the purpose of what their country cared about
from making money to happiness, and changed the measures accordingly.
And now, a lot of countries are trying to have those measures, and
also Bhutan does actually have kind of happier people based on those measures.
Compared to countries that are around them, and
compared to countries that have a lot harder GDP.
So basically, that's a classic changing the whole purpose of the system,
which is interesting for the power it has, but also interesting for the,
that was a pretty simple change, right?
I mean yeah, it's hard to get all the laws enacted and things like that.
But it wasn't like they had to invent some new technology or anything like that,
it's just we're going to focus on something else.
And then soccer, the difference between kind of the professional
soccer system versus the soccer system that I was exposed to growing up, right?
So the professional system, the purpose is to make money, and so
then you have all these different kind of things that are happening that
are aligned with making money.
So the example that's in the book is the falling balls in Baltimore where we were
playing an indoor game in the Baltimore Arena.
And as they were announcing the players the smokes coming out and
the lights are flashing and this massive ball dropped down from the ceiling.
And it stopped like six feet above my head.
But it was pretty scary before I realized it was going to stop.
>> [LAUGH] Yeah.
>> That's the falling balls example.
