“What I'm trying to describe is that it's impossible to get out of your skin into somebody else's…. That somebody else's tragedy is not the same as your own.”

Fox News interview (May 2004)
Context: There are four ways in which you can spend money. You can spend your own money on yourself. When you do that, why then you really watch out what you’re doing, and you try to get the most for your money. Then you can spend your own money on somebody else. For example, I buy a birthday present for someone. Well, then I’m not so careful about the content of the present, but I’m very careful about the cost. Then, I can spend somebody else’s money on myself. And if I spend somebody else’s money on myself, then I’m sure going to have a good lunch! Finally, I can spend somebody else’s money on somebody else. And if I spend somebody else’s money on somebody else, I’m not concerned about how much it is, and I’m not concerned about what I get. And that’s government. And that’s close to 40% of our national income.

Context: I want to leave my daughter, and my grandchildren I hope to have and all these young people, a better world. And I think the reason you should do things for other people at bottom is selfish. There is no real difference between selfish and selfless if you understand how the world works. We all tied together. [... ] Everytime you cut off somebody else's opportunity you shrink your own horizon.

You didn't get there on your own. I'm always struck by people who think, "well, it must be because I was just so smart." There are a lot of smart people out there. "It must be because I worked harder than everybody else." Let me tell you something — if you've got a business, you didn't build that. Somebody else made that happen.
Splices two parts of a speech in Roanoke, Virginia on (see above). Full quote:
<p>There are a lot of wealthy, successful Americans who agree with me — because they want to give something back. They know they didn't — look, <span style="color:darkgrey">if you've been successful, you didn't get there on your own.</span> <span style="color:grey">You didn't get there on your own.

There was a great teacher somewhere in your life. Somebody helped to create this unbelievable American system that we have that allowed you to thrive. Somebody invested in roads and bridges; <span style="color:darkgrey">if you've got a business, you didn't build that. Somebody else made that happen.</span> The Internet didn't get invented on its own. Government research created the Internet so that all the companies could make money off the Internet.</p>
