Gorick Ng, career advisor at Harvard, tried to learn about the world of work at an early age, helping his mother search job listings and send out resumes. To launch his own career, he studied hard in school, secured an Ivy League education, and landed a plum job. But he still found himself struggling - as many first-generation college graduates do - because he didn’t understand workplace norms in the way that his (mostly white, middle- to upper-class) peers did. While they'd been taught how to network, angle for promotions, and "speak the language," he was left to figure it out on his own. Now, Ng counsels young people on how to avoid those mistakes and take on their first job in a way that puts them on the fast-track to success. He's the author of the book "The Unspoken Rules: Secrets to Starting Your Career Off Right."
