My happiness is tied to how I feel about myself.

Barack and I were both raised by families who didn't have much in the way of money or material possessions but who had given us something far more valuable - their unconditional love, their unflinching sacrifice, and the chance to go places they had never imagined for themselves.

I was blessed throughout my entire career. I had people rooting for me. It started with my parents, but it extended to almost every teacher that I had. Even when I was a young lawyer, there were other women and men in the firm who took me under their wing.

I love that we can trust Barack to do what he says he's going to do, even when it's hard - especially when it's hard.

I want to feel like the things I did made a difference. That's one of the reasons I spend time greeting people on rope lines, because I'm always thinking, 'Maybe this interaction, particularly if I'm meeting kids, will change someone's life.' That's how I think about the work I do as First Lady. It's a rare spotlight. I want to make sure I don't waste it.

Politics is a waste of time.

Every elected official on this planet should understand - don't play with our children, don't do it.
