How do you do it?

For the work at home parents out there - how DO you do it? 

Those of you who have to be on the clock so many hours per day -- or have a large amount of work to get done -- how do you do it?  I can't imagine trying to work a 9-5 at home without being driven to distraction -- for me that might mean walking away from whatever I need to do because I cannot concentrate. 

This is the exact reason I am rambling in this little post -- I can't stay on task with the one I WANTED to write because I am distracted by a dirty diaper, a spill, a snack, a potty emergency, a change of clothes, a laundry load, a cat-box, a barking dog, dishes, a spill, a vacuum... and it's just 9am.

So - how DO you do it? 

Do you just ignore everything and let the house and kids, go?  I wouldn't want to be at the other end of the day and be greeted by the path of the tornado. 

I think if I had a work-from-home job and no distractions I would be pretty freaking amazing.  But, then again, I would not require a work-from-home job if I HAD no distractions, I guess?
