Marketers are bystanders.

In the words of Peter Drucker:

The bystander sees things neither actor nor audience notices. Above all, he sees differently from the way actors or audience see. Bystanders reflect, and reflection is a prism rather than a mirror; it refracts.

As a marketer, you operate in this middle space, at a slight remove.

Your job is—to continue the metaphor of actors and audience—to manage the fourth wall. The vital point where performance meets audience and the magic happens (or doesn’t).
