For me, kitchen and bathrooms need to be clean. Then the living room, if there is clutter, I put it all in a wash basket, vacuum/mop, and dust. Then I deal with the clutter as and when I can. Bedrooms come last on the priority list for me, as no one else sees them! I always keep my entrance hallway clean in case I have a delivery.
There is a website that has a swear word in the title so I shan't link it, but it's aimed at people who've really let the house get on top of them, for whatever reason, workaholic, grief, depression, 5 kids under 5, and it suggests to go around the entire house with a bin bag for the rubbish, then to go round and collect all the laundry, then put a load on, then to go and collect any other clutter or things left on floors, then assess the situation. You'll feel a lot more motivated when the whole place looks a bit tidier just after a couple of whiz-arounds
