In recent years, we've become enamored with our own past success. Lulled into complacency by the glitter of our own achievements. We've become accustomed to the title of Military Superpower, forgetting the qualities that got us there. We've become accustomed to our economic dominance in the world, forgetting that it wasn't reckless deals and get rich quick schemes that got us where we are, but hard work and smart ideas, quality products and wise investments.

The wort terrorist attack in American history also brought out the best in our country...We are United as Americans.

I actually think, when you're young, ambitions are somewhat common - you want to prove yourself. It may grow out of different life experiences. You may want to prove that you are worthy of the admiration of the demanding father. You may want to prove that you are worthy of the love of an absent father.

That's what building a body of work is all about. It's about the daily labor, the many individual acts, the choices large and small that add up over time, over a lifetime to a lasting legacy. It's about not being satisfied with the latest achievement, the latest gold star, because the one thing I know about a body of work is that it's never finished. It's cumulative. It deepens and expands with each day you give your best. You may have setbacks and you may have failures, but you're not done.

We've achieved this historic progress through diplomacy, without resorting to another war in the Middle East. I want to also point out that by working with Iran on this nuclear deal, we were better able to address other issues.

The number of Americans killed since 9/11 by terrorism, it's less than 100. If you look at the number that have been killed by gun violence, it's in the tens of thousands. And for us not to be able to resolve that issue has been something that is distressing.

Sometimes Hillary Clinton doesn't get the credit she deserves. But the fact is, Hillary is steady, and Hillary is true.
