[On the difference between mothers that work outside the home and those that don't]  "Let's start with the main difference:  I think while all mothers deal with feelings of guilt, working mothers are plagued by guilt on steriods.  No matter how many times I tell myself that I am what I am -- and that I cannot imagine myself not working (it's such a big part of who I am), the truth is I will always keep comparing myself to my own phenomenal stay-at-home mom, for whom the universe began and ended with her children.  She was the ultimate nurturer -- and she set the good mother bar very high indeed."
