The one way to get me to work my hardest was to doubt me.

It was clear to me that if I could get through Princeton at the top of my class, I could do anything in the world.

When I get up and work out, I'm working out just as much for my girls as I am for me, because I want them to see a mother who loves them dearly, who invests in them, but who also invests in herself. It's just as much about letting them know as young women that it is okay to put yourself a little higher on your priority list.

Another suggestion is to cook a meal, maybe not every night, but a couple more times a week than you usually do. That way you have leftovers, and you take your lunch to work.

A candidate is not going to suddenly change once they get into office. Just the opposite, in fact. Because the minute that individual takes that oath, they are under the hottest, harshest light there is. And there is no way to hide who they really are.

For me, education has never been simply a policy issue - it's personal. Neither of my parents and hardly anyone in the neighborhood where I grew up went to college. But thanks to a lot of hard work and plenty of financial aid, I had the opportunity to attend some of the finest universities in this country.
