If you’re like many people I know, you may be uncomfortable sharing personal information about yourself with co-workers. It may be because you grew up with humble origins and are surrounded by people who talk about foie gras, summering in the Hamptons or golf foursomes; you may not want to talk about your lousy childhood and get pity from others. Or maybe you are an immigrant to the U.S. and part of a non-Christian religion, you might feel your traditions, family stories and holidays don’t connect with the majority of people around you; you don’t want to be a curiosity. If you’re a woman or minority, you may feel a need to emphasize your professional side to maintain enough respect; you don’t want to discuss topics that undermine your authority and expertise.
