How do you find yourself?

I was at a friends house today. As the kids were all playing we were chatting about kids, life and other that other good stuff. We came upon he subject of finding yourself. I don't know who I am anymore other than "Mom". Somewhere along the last 4 years I have "lost myself". I don't even remember what I used to like to do. We get so caught up in Mommy that I think we (as mother's) tend to ignore ourselves. I'm the first to admit my kids come before me (as I think they should). When we go out I don't care how I look as long as my kids look presentable (It does help if I don't have any spit up on my shoulder) So my question is..... How does one find themselves after they have been lost? Maybe and Manicure and pedicure will do the trick? :)
