Rose Tyler: It was a better life. I don’t mean all the traveling and… seeing aliens and spaceships and things, that don’t matter. The Doctor showed me a better way of living your life. You know he showed you, too. That you don’t just give up. You don’t just let things happen. You make a stand. You say no. You have the guts to do what’s right when everyone else just runs away!

From Doctor Who – Season 1 Episode 13: ‘The Parting of the Ways’ (1×13)
