Believe That Dreams Come True.... Because They Do :) So Go And Get It :)

Christopher Gardner: Hey. Don't ever let somebody tell you... You can't do something. Not even me. All right?

Christopher: All right.

Christopher Gardner: You got a dream... You gotta protect it. People can't do somethin' themselves, they wanna tell you you can't do it. If you want somethin', go get it. Period.
