To my remarkable staff: For 8 years--and for some of you, a whole lot more--I have drawn from your energy, and every day I tried to reflect back what you displayed: heart and character and idealism. I've watched you grow up, get married, have kids, start incredible new journeys of your own. Even when times got tough and frustrating, you never let Washington get the better of you. You guarded against cynicism. And the only thing that makes me prouder than all the good that we've done is the thought of all the amazing things that you are going to achieve from here.
