Well, I think you get used to it (my own experience). For some reason I don't see it until guests are on the agenda. I don't like having a dirty/messy house but I get overwhelmed when I think about trying to clean it. My mom thinks it has something to do with perfectionist tendencies...because I can't do it perfectly, I get overwhelmed, throw up my hands, and quit.
My husband grew up with a very organized mother. Her house was clean and home cooked meals were on the table for breakfast and supper. For years he silently compared me to his mom. My lack of homemaking abilities was a real sore spot for years. Then, he got a job at church where he visited other homes weekly. He realized that many people weren't like his mom. He is now a lot more relaxed about the state of our home and tells me to chill out when I start getting stressed.
I also wonder if the size of house makes a difference. We have five people and a medium dog living in a 1047 sq ft house. We don't have a designated space for homeschooling so there is stuff stashed all over the house. Oh, and we actually park in our garage instead of using it as a storage space.
I admit I'm messy and yes, it bothers me. Apparently not enough to change.
