Hi Ks,
I am in that very same trench right with you. I'm learning slowly but surely that it takes much less energy to start a task if it is part of a routine. If you just automatically take a load of laundry and toss it in every morning on your way to the kitchen for your morning coffee, you'll have a load of clean clothes ready to go into the dryer before you're even fully conscious!
The idea of inviting people over is a great one too.
Take it one step further and enlist a friend to be your "home keeping buddy". Decide which day of the week is best for both of you to be your "grocery shopping day", "laundry day", "dusting and vacuuming day", "planning day", etc. Call each other to ask, "How's that dusting coming along?" This will make you accountable to another human being and help with your feelings of isolation.
I'm convinced that our generation was done a great disservice. We were raised with the idea that home keeping is not a job to be desired or proud of when done well. Consequently, our parents did not teach us the right way to do many of the tasks involved in keeping a home, or the reasons for doing things a certain way. Only if you were raised by your grandmother were you taught to take pride in a well-scrubbed kitchen floor.
Believe me, my kitchen floor is in no condition for anyone's grandmother to brag about, but I am slowly learning to value the time, brain power, and skills involved in keeping a home that I can be comfortable living in and inviting people into.
Realize that in order to maintain a home that you feel proud of on a daily basis, you will have to overcome what your mother didn't teach you, what society doesn't appreciate, and the fact that so many of the activities involved in keeping a home are mundane and seemingly never ending! That's a lot to overcome. But you can do it. I'm actually making tangible progress, and that's saying something!
So, keep at it, but don't feel guilty that you're not there yet. Guilt will only slow you down.
Additionally, don't do it alone. Put an old sock on that 2year-old's hand and put her to work dusting the surfaces without breakables on them. Suggest to your husband that one Saturday a month should be spent doing the seasonal or yearly maintenance for your home. If you use Outlook, you can program vacuuming the refrigerator coils as a reoccurring appointment that happens every 6 months.
Finally, to support you in your efforts of establishing routines, setting your priorities, and to answer the question of how to fold a fitted sheet to make it look as tidy as the flat one, get a hold of a book called Home Comforts. There is so much information in this book that it is a tangible reminder that no one can do it all, perfectly, all the time. Use it as your home-keeping bible and reference book. It's awesome.
Sometimes if I can't stand my slovenly self any longer, and decide that something must be done, I'll start by opening this book. Pretty soon I'm off the couch doing something productive.
Let me know how you get on.
