1. Astronaut Hillary: Hillary has mentioned in many speeches that her childhood goal was actually to be an astronaut, but that she was rebuffed after she wrote in to NASA expressing her interest in traveling to space. In the early 1960s, when she would have written, NASA only accepted men as astronauts. In fact, it was a heated topic of discussion at that time whether women should be allowed to participate in the space travel program.

2. Wellesley Commencement Speech: As Hillary鈥檚 cohort prepared to graduate from the women-only liberal arts college in 1969, they decided they wanted to hear from someone who鈥檇 never been invited to speak at a Wellesley convocation ceremony: a member of the graduating class.

3. Working on the Watergate Committee: Contrary to what some believe, Hillary Clinton was not fired from the committee investigating whether then-president Richard Nixon should be impeached for his involvement in the Watergate scandal.
