R. Keith Sawyer quotes:

While in the process of executing an idea, creativity happens not with one brilliant flash but in a chain reaction of many tiny sparks.

In an improv group and a successful work team, the members play off one another, each person's contributions providing the spark for the next. Together, the improvisational team creates a novel emergent product, one that's more responsive to the changing environment.

The way you look at the world determines how creative you can be.
