sometimes it helps when i make a list that looks like this:
scott joni
our room kitchen
kitchen dining room
playroom our room
etc
then we set the timer for 5 minutes and do whatever we want in that room. i don't get on scott if he does something i wouldn't have done and vice versa because different things are important to us. if a room's horrible, i put it on both of our lists and sometimes twice on both of our lists but no matter what we can't stay in the room more than 5 minutes and maybe 30 seconds after the timer goes off.
we usually get the whole house reasonable in 30-60 minutes this way, even if it's totally awful. and it usually motivates me to go back and fine tune things.
i hope you have a wonderful family dinner. i'm going to revisit my lists and figure out what to do next. check in if you have time. i promise i'll try not to write as much next time!
