Adapting "how to be an entrepreneur" to non-coaching business

I am currently doing the “How to be an entrepreneur” course, and find it very difficult to identify with what’s being thought there.

For example: The first question on one of the worksheets is: “Does your problem fit into one of these broad categories? WEALTH HEALTH RELATIONSHIPS If yes, move on. If not, change your market.”

My product does not concern any of these categories. It’s TV documentaries that I sell to public TV channels. What now? How do I “change my market”?
