I'd move into a house that allowed my wife & kids to have more property for horses & horse related stuff
I'd put in a food forest, silvo pasture & raise some cows, & more pigs.
I'd put in a nice shop, wood working, metal working, laser cutter, cnc, 3d printer or 2. that way I could get back into wood working & just play doing stuff
I'd probably also take a really long trip (30-60 days) with my family to see the US,
I'd spend more time with my kids camping, fishing, horseback riding, etc.
Then possibly go walkabout when their older.
