I've come to embrace the notion that I haven't done enough in my life. I've come to confirm that one's title, even a title like president of the United States, says very little about how well one's life has been led. No matter how much you've done or how successful you've been, there's always more to do, always more to learn, and always more to achieve.

Africa is on the move; a new Africa is emerging!

And I will do everything that I can as long as I am President of the United States to remind the American people that we are one nation under God, and we may call that God different names but we remain one nation.

Let it be said to our children's children that when we were tested we refused to let this journey end, that we didn't turn our back nor did we falter; and with eyes fixed on the horizon and God's grace upon us, we carried forth that great gift of freedom and delivered it safely to future generations.

Part of what we have to do a better job of, if our democracy is to function in a complicated diverse society like this, is to teach our kids enough critical thinking to be able to sort out what is true and what is false, what is contestable and what is incontestable. And we seem to have trouble with that. And our political system doesn't help.

What used to be racial segregation now mirrors itself in class segregation, this great sorting (has) taken place. It creates its own politics. There are some communities where not only do I not know poor people, I don't even know people who have trouble paying the bills at the end of the month. I just don't know those people. And so there's less sense of investment in those children.

I think that [having not a lot of time sweating the details] can be both a strength and a weakness. I think it depends on how [Donald Trump] approaches it. If it gives him fresh eyes, then that can be valuable. But it also requires you knowing what you don't know and putting in place people who do have the kinds of experience and background and knowledge that can inform good decision making.
