Can I suggest that you focus on ways to create outsized value with software? This puts you several steps ahead of the game. Speaking in generalities, the "passive income" crowd don't tend to actually build businesses and often don't create sustainable, defensible value in their projects. If you build a business with sustainable, defensible value, then "all" you need to do from that point is figure out the right combination of algorithms and employees such that your personal time investment is sufficiently low such that it hits your "passive" threshhold.

Just read your list. Awesome. Can you expand on number 2 a bit? Are there other similar questions that can get people talking about solutions amenable to a software product?

I like the Excel idea a lot, I'm hoping to have several such questions.
