The Catalyst of Gambling

[Diana]

There is also the distinction, risk-taker. For instance, entrepreneurs must take risks and they "gamble" all the time that what they are pouring their energy into will yield something (it's not blind gambling as they have presumably though things out). This is an aspect of creative energy— to create something one may take risks. 

So if a society has no entrepreneurs or risk-takers in this way, things could get pretty stagnant.
