As one single person running an entire household, especially one house with 4 people and a dog living in it, organization is not only important, it's vital.
Things run in a certain flow, all the time. Big things, little things.
For example, last Sunday I went to Six Flags with my kids instead of buying groceries. Sunday night I had Mr. Wonderful stay with them after they went to bed so I could get groceries. I got home late and without everything I needed, which sent me to the store extra times every day last week. Which meant I lost time doing things like laundry, cleaning, and work. (because with three kids, you cannot just run in and out of a store).
Right now, my laundry is piled to the ceiling. You cannot see the floor in my laundry room. I am down to my last set of clothes. I haven't done laundry because the laundry baskets are full of clothes needing to be put in the kids drawers. I haven't put the laundry in the drawers because their drawers are overfilled of clothes that don't fit them. Their drawers are overfilled of clothes that don't fit them because I haven't gone through and stored their winter clothes or boxed the clothes that don't fit because there is no room in my garage. There is no room in my garage because there is a crib in there waiting to be sold, along with boxes of trash that need to be cleaned out. I haven't sold the crib or cleaned out the boxes because there JUST ISN'T ENOUGH TIME IN. THE. DAY.
One of these days I will use my weekend without kids to get these things done. A weekend when I don't have to cram all the work I didn't get done during the week with them here into, or am not so exhausted from the week that all I want to do is sleep.
Sleep...omg that sounds so heavenly right now.
