“Living, just by itself - what a dirge that is! Life is a classroom and Boredom's the usher, there all the time to spy on you; whatever happens, you've got to look as if you were awfully busy all the time doing something that's terribly exciting - or he'll come along and nibble your brain.”

The Web version of the ad http://www.youtube.com/watch?v=4Lr49t4-2b8 uses a <span style="color:grey">longer misquote</span>: "If you've been successful, you didn't get there on your own. 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. 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 —</span> there are a whole bunch of hardworking people out there.</p><p>If you were successful, somebody along the line gave you some help. 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>
