I think the most important thing for young people is that they're not trapped in the past. And human progress is driven by looking at a problem with fresh eyes, with new eyes. [...] And that's the power of young people, is asking why. Little kids, they naturally do that, right? When you talk to a four-year-old or a five-year-old, six-year-old, you tell them to do something -- "Why?" "Why?" And sometimes, as parents, we try to say, "because I told you so." And we don't want to talk about it, right? But that impulse to ask why is actually what drives human progress. [...] Vision is important, but then you also have to have the persistence to keep working to make progress. And I always tell young people to have big dreams, but then also be willing to work for those dreams. It's not going to come right away.

The trick is not caring that it hurts.

I know these are difficult times. I know folks are worried. But I also know that now is not the time for fear or panic. Now is the time for resolve and steady leadership. Because I know we can steer ourselves out of this crisis. This is a nation that has faced down war and depression; great challenges and great threats. We have seen always that mountaintop from the deepest valley. We have always risen to the moment when the moment was hard – and we can do it again. We can restore confidence in our economy and renew that fundamental belief – that here in America, our destiny is not written for us, but by us.
