介绍： Americus Reed knows what it feels like be an outsider. To be surrounded by strangers, and to have to figure out how to fit in.

Today he's a professor of marketing at the University of Pennsylvania. But when he was 17, he was the new kid — one of a handful of black students bused to a predominantly white school. He wanted to be accepted. So he came up with a plan: He would become a social chameleon.

"I sort of settled on this idea that I would try to be...a boundary-spanner," he says. "So I hung out with the nerds, I hung out with the jocks, I hung out with the musicians."

As he spent time with these different cliques, he noticed that each had its own set of badges, its own language. And he realized that if he could speak that language, adopt those badges, he would start to blend in. So he started wearing the things the other kids wore. With the athletes it was Nikes. With the musicians, Chuck Taylors. With the hip hop kids, Adidas – but without the shoelaces. It was like a costume, but deeper.

"A brand is so much more than a tagline or a logo," he says. "It is more of a meaning system."
