I so agree with the comment about doing this alongside and with the support of your dp. We have been in our house for 2 years; before that we were in our other house for 5, and before that our apartment for 2, I think ... well, I was for almost 2, dh was there with me for 1. Anyways ... lots of years living together. And each move, we brought the stuff with us. I have been telling him for years that I cannot live in chaos - that emotionally it is extremely hard on me (depression and anxiety), plus it really feeds my SID. But he didn't "see" it. He felt for me and tried to help me, but because he didn't "see" the chaotic lifestyle, he was really, unable to help. This summer, due to a major home improvement project (new paint, new carpet, new fixtures in our bathroom), he finally "saw" it all. And it has made a *huge* difference. He is now helping me get rid of it because he can finally see and feel the toxic affect the clutter and chaos and mess can have on us all. So, I highly agree that simple living needs committment from your dp (at least in my case it is true).
For us, decluttering, simplifying, and streamlining is huge for simple living. We have cut the toys in half; we have cut our books down by probably 30% of what they were (we had over 1000 books in our house and were buying more bookshelves to keep up!
). We are cutting misc. crud by 50%, purging the garage and shed, and keeping what we actually use and need. We eliminated the "playroom" and made it into a bedroom for ds#3. Each boy now has their own space (we are very grateful we have a house that is big enough for them each to have their own room), with minimal toys, and a place for everything. If something doesn't have a place in their room, then we either make one (if it's something that should be in there) or it doesn't go in there to begin with. The same is true with our living spaces. I want a simple house with beautiful things that are given their place and space. If something does not have a definite function and/or make our house beautiful/inviting/welcoming, then I don't want it in here.
We are also working on growing our own produce. For us, it is important to find local and organic food. But, we often don't make time to get to the Farmer's Market. Our local HFS carries some food grown in-state, but also carries much imported produce. So, we are slowly growing our green thumbs, and expanding our produce-growing and storing abilities.
Like a PP, I have decided that I will only buy craft stuff (for me, that is mostly fabric) if I know exactly what I'm going to do with it and actually have the time planned to do it. So, if I want to sew the boys all pajama bottoms, then I first need to schedule the time (talk with dh about a Saturday or Sunday where he could take the boys to the park for a couple hours), look through what I already have (fabric, thread, and pattern), and only then if I need something to complete the project, go to the fabric store the night before my sewing "date" to get what is needed. We plan on refurbishing our dining room chairs and I will need fabric for that. But, as much as I'd love to go wander the aisles of JoAnn's, I am waiting until the old fabric is off the chairs, I have measured and multiplied, and I know exactly what I need.
We are also trying to adopt the "one thing in - one thing out" motto. If the boys get something new to play with, then something of equal size or type should find its way to the Goodwill. We we decluttered ds#1's toys, we realized he had 4 or 5 Batman action figures, all basically the same size and function. We also realized he doesn't play with them but likes "collecting" them. So, he chose he 2 favorite and donated the rest. If he wants a new/better/different looking one, then one of the old ones goes.
Finally, we are trying to be extremely mindful in our shopping trips. No more just walking around Target, Ikea, or the mall. If we need (or want - I don't want to completely deny ourselves wants, but be more mindful of them), then we plan a specific shopping trip, take a list, and really stick to it. I want to know what is going to come in the house and where it will go/fit before it comes here physically.
Phew ... sorry that turned into a novel. It is really nice, though, seeing that all typed out because some days I do wonder if we are really doing things more simply or if I'm just pretending we are.
