Back at Work

Well, my maternity-leave ended and I've been back at work full-time for about 7 weeks now. I was dreading going back to work because I really loved being at home with my kids for the last year and living around my own family schedule... but I have to say, being back at work has been great! I guess I really must enjoy my job because it feels so good to be back at work. The house has suffered a little. I find the mess piles up in a sneaky way during the work week. All of a sudden, before I know it the house looks like a bomb went off or something. That's the one crappy thing about not having any time to clean during the weekdays. I'm more of a morning-energy person, I really don't have much energy at night, especially after coming home, making dinner and getting the kids to bed. C'est la vie, right?! :) Although I really am trying to figure out a way to at least keep the house looking good enough so that I don't die if I find out I have last minute, drop-in guests coming over (AKA the in-laws). I'm thinking about purging my house... anyone have any good tips for getting rid of stuff? I'm not exactly a pack rat, yet I have trouble deciding what I need and what I don't.
