When Anna Eshoo was in middle school she wanted to be an eye doctor. She didn't know why, but she liked going to the doctor and all the things they did. But a teacher told her to forget her dream. "Girls aren't good at math," she told her. Eshoo, who has served in Congress for more than 20 years, was at Campbell Middle School Thursday to encourage girls -- and boys-- not to be held back from their dreams.
