New investments in cyber security and the modernization of our military will spur substantial new job creation in the private sector and help create the jobs and technologies of tomorrow.

I am very underleveraged. I have a great company. I have a tremendous income. And the reason I say that is not in a braggadocios way. It's because it's about time that this country had somebody running it that has an idea about money.

I've known people who had fantastic ideas, but who couldn't get the idea off the ground because they approached everything weakly. They thought that their ideas would somehow take off by themselves, or that just coming up with an idea was enough. Let me tell you something - it's not enough. It will never be enough. You have to put the idea into action. If you don't have the motivation and the enthusiasm, your great idea will simply sit on top of your desk or inside your head and go nowhere.
