The problem is that the way [President] Bush has done it over the last eight years is to take out a credit card from the Bank of China in the name of our children, driving up our national debt from $5 trillion dollars for the first 42 presidents - number 43 added $4 trillion dollars by his lonesome - so that we now have over $9 trillion dollars of debt that we are going to have to pay back. [That's] $30,000 for every man, woman and child. That's irresponsible. It's unpatriotic.

All the good things that are happening in America don't get reported on a lot.

Who is Barack Obama? Contrary to the rumors you have heard, I was not born in a manger. I was actually born on Krypton and sent here by my father Jor-El to save the Planet Earth. Many of you know that I got my name, Barack, from my father. What you may not know is Barack is actually Swahili for 'That One.' And I got my middle name from somebody who obviously didn't think I'd ever run for president. If I had to name my greatest strength, I guess it would be my humility. Greatest weakness, it's possible that I'm a little too awesome.

And I want to work with this Congress, to make sure Americans already burdened with student loans can reduce their monthly payments, so that student debt doesn't derail anyone's dreams.

Physically, I feel probably as good as I've ever felt. And I've got as much energy as I ever did. But what you feel after eight years - and I think you'd feel this no matter what, but anytime you have a big transition, it gets magnified - is time passes.

One of the things that you learn, having been in this [President's] office for four years, is the old adage of Abraham Lincoln's. That with public opinion there's nothing you can't do and without public opinion there's very little you can get done.

For too many of us, it's become safer to retreat into our own bubbles, whether in our neighborhoods or on college campuses, or places of worship or especially our social media feeds, surrounded by people who look like us and share the same political outlook and never challenge our assumptions. And increasingly, we become so secure in our bubbles that we start accepting only information, whether it's true or not, that fits our opinions, instead of basing our opinions on the evidence that is out there.
