The most important lesson I think I could impart is don't let anyone determine what your horizons are going to be. You get to determine those yourself. The only limitations are whatever particular talents you happen to have and how hard you're willing to work. And if you let others define who you ought to be, or what you ought to be because they put you in a category, they see your race, they see your gender and they put you in a category. You shouldn't let that happen.

Our work has only begun. In our time we have an historic opportunity to shape a global balance of power that favors freedom and that will therefore deepen and extend the peace. And I use the word power broadly, because even more important than military and indeed economic power is the power of ideas, the power of compassion, and the power of hope.
