From Shakespeare in Love:

Henslowe: Mr. Fennyman, allow me to explain about the theatre business. The natural condition is one of insurmountable obstacles on the road to imminent disaster.

Fennyman: So what do we do?

Henslowe: Nothing. Strangely enough, it all turns out well.

Fennyman: How?

Henslowe: I don't know. It's a mystery.
