Get professional help

There's no rule that says you have to do it all yourself.  There is a whole world of people outside your door (and maybe even in your house) who are capable of tackling parts of your project that you can't handle, or don't have the time for.  Take advantage of them if that's what it takes to get the job done! After all, success is the issue, not proving you're Superman or Superwoman. 

For example, let's say that your goal is to get your house ready for a move or an open house if you're trying to sell.  If finances permit (and even if they don't, it can still be worth it in terms of mental health preserved), call in a maid service for a day to do basic cleaning, hire professional carpet cleaners, take the animals to a kennel and send the kids off with your sister to Chuck E.  Cheese.  Let the pros handle the crummy stuff while you focus on ensuring the safe transport of Great Aunt Gemma's priceless Ming vase to your new home, or while you get busy filling the house with that scent of baking bread that your realtor swears will close the sale.
