I was given advise from a shrink once, on this very subject. I was too busy or too tired to make my home meet my own expectations. His advise:
Take the thing that is bothering you the most, and use those few minutes a day to fix it.
For me, it was dog hair balls gathering along the baseboards of the hardwood floors. Those tumble weeds made me crazy. Seriously, it only takes 5-10 minutes to sweep them up. Don't clean the whole living room (or dining room), sweep up the hair balls.
Toothpaste and hair in the bathroom sink, drove me nuts. Don't clean the whole bathroom. It takes 5-10 minutes to clean the sink.
Use your 5-10 minutes to do what's bothering you the most. Before you know it, the hair balls are gone, the bathroom sink is clean, and you're using your 5-10 minutes for that annoying mailbox pile.
This advise helped me a lot. It made me not feel so overwhelmed all of the time. Don't tackle the room. Tackle the thing in the room that is bothering you the most. Remember, doors were meant to be closed (like the dreaded laundry room)! I hope this helped. Keep me posted.
