You know, one of the things I think you understand as president is you're held responsible for everything, but you don't always have control of everything, right?
I do solemnly swear that I will faithfully execute the Office of President of the United States, and will to the best of my Ability, preserve, protect and defend the Constitution of the United States
I'm just beginning to live the next chapter of my life. In other words, politics - being governor and president - is not the end of my life. It's a chapter.
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.
So I analyzed that and decided I didn't want to be the president during a depression greater than the Great Depression, or the beginning of a depression greater than the Great Depression.
