Barack Obama said this quote
“ But that’s part of what makes America wonderful, is we always had this nagging dissatisfaction that spurs us on. That’s how we ended up going west, that’s how we--“I’m tired of all these people back east; if I go west, there’s going to be my own land and I’m not going to have to put up with this nonsense, and I’m going to start my own thing, and I’ve got my homestead.” ...It is true, though, that that restlessness and that dissatisfaction which has helped us go to the moon and create the Internet and build the Transcontinental Railroad and build our land-grant colleges, that those things, born of dissatisfaction, we can very rapidly then take for granted and not tend to and not defend, and not understand how precious these things are. ”
