This echoes the commentary in Rework that one should always monetize the things you create as a by-product of your main goal.

In the electronic sphere, Rework suggests that musicians make "making of" documentaries (a natural side-product of having to make a record) and startup founders share their knowledge gained while in pursuit of their main dreams. Here, the same example is given with Google's bond trading (a side-product of a massive search database is a massive financial database) and similar.
