My second favorite movie ever (my first is Purple Rain).
But for sure I can relate to that take a chance line in the movie. It's one of the pivotal lines in the movie, cleverly spoken by an extra instead of one of the main characters, which gives it a real-world feel, as if a message for everyone watching the movie.
And you are right. We should take more chances on the out-of-the-ordinary so that we may experience the extraordinary.
