You want to get along with a Director? Ask him what he thinks. You want to get along with an Explorer? Ask him what he does. You want to get along with a Builder? Ask him who he knows. And you want to get along with a Negotiator? Ask him how he feels.”

For the Explorer, the word is adventure. For the Builder, it’s family. For the Director, it’s intelligence. And for the Negotiator, it’s passion.”

The Explorer, defined by high dopamine activity, is adventurous, novelty-seeking, creative.

The Builder, with high serotonin activity, is cautious, conventional, managerial. The

Director, pumped up with testosterone, is aggressive, single-minded, analytical. The

Negotiator, more estrogen-influenced, is empathetic, idealistic, a big-picture thinker.

“Like attracts like” and “Opposites attract,” are each true about half the time. Explorers are drawn to Explorers, and Builders to Builders, but that Directors are attracted to Negotiators, and vice versa.
