Parents often tell their children that they can aspire to whatever careers they wish. But that wasn't as true only a few decades ago, before women began working outside the home and making career inroads alongside the guys. Starting in 1993, the Ms. Foundation encouraged parents to take their daughters to work to teach younger girls to embrace that "I can do anything" ethos [source: Ms. Foundation]. Take Our Daughters to Work Day was expanded to Take Our Daughters and Sons to Work Day in 2003, and it happens annually on the third Thursday in April. With millions of parents and kids participating each year, it has quickly become an American family tradition. In 2011, First Lady Michelle Obama even hosted a group of children whose parents work at the White House for Take Our Daughters and Sons to Work Day.
