So far, so good

I've recently adopted the colloquialism "so far, so good" from somewhere. So the other day I'm talking to my coworker about something and I say, "so far, so good" and she asks if I've ever seen the movie La Haine. From the movie:

Heard about the guy who fell off a skyscraper? On his way down past each floor, he kept saying to reassure himself: So far so good... so far so good... so far so good. How you fall doesn't matter. It's how you land!
