I don't know if this is actually useful, but I have come to use Wunderlist for projects, not because it's that good, but because it sucks less and has a very low learning curve. When I check something off it feels good, and even the act of structuring something into a set of subtasks feels like I am not completely at sea.

(Also, shared lists so we don't mess up nearly as badly on the groceries.) And third or fourth the cleaning service.
