I am looking forward to getting out of the bubble. I am glad that I'm leaving this place at a relatively young age, at 55. So I have the opportunity for a second maybe even a third act in a way that I think would be tougher if I were, you know, the age of some presidents when they left.

Going through the legislative process is always better, in part because it's harder to undo.

There's no doubt that I'm a better president now than when I first took office. This is not a job where there's a manual, and over time you get a better sense of what's important, what's not, how to see around corners and anticipate problems, as opposed to just managing problems once they've arrived.

Our patience is not infinite. We're not willing to let this go on forever.
