I feel you girl! I am not all that bothered by things being out of place either and I WISH it bugged me, but it doesn't.
As long as the dishes are washed, the clothes are clean, and there are no moldy science experiments growing under the bed, I 'm fine.
I wash dishes each day and keep my bathroom and kitchen clean each day. The kids room--messy. They pull every toy they own out. My living room stays clean if I keep them out of it, so I don't have a problem there. I never stay in my bedroom but to sleep, so it's clean all the time. The only other room that gets messy is what I call my study room and it is an organized mess, so I'm happy.
I don't think it's out of control, because when I watch "How Dirty is your House" and those organization shows on TLC and HGTV, I'm disgusted because there is food rotting everywhere and those people can't even walk around and you can't see the floor.
It's not to that level in my house, so I'm doing alright I guess.
The really funny thing is I used to clean my patient's rooms all the time--I couldn't stand for them to be dirty.
I really don't have any advice for you other than to just keep the hot spots clean--kitchen and bathroom--and don't let the kids eat outside of the kitchen. That way you don't get any houseguests if you know what I mean.:chuckle
Oh and after you're a FNP, you can hire a maid.
