This is a challenge I've come up with and am just now starting. I don't really have any rules. The goal though, is to live off what you can make/grow at home. You need Seasons, Freetime, and Business expansions for this challenge.

To make money you must make and sell items you sew, foods you grow, or/and old cars you fix and sell. You must grow foods or catch fish to eat.

The point is to see how long you can go on like this. It's basically a legacy challenge with the added rule that you can only make money off home grown/made items.
