Do you feel like you buy too much stuff or that you are trapped by all of your belongings? I know I sometimes do. Even if you aren't feeding into the standard commercialism of electronics and cars and clothing, it's easy to buy too many things to feed other, more sustainable hobbies.
Like gardening, sewing, knitting, home brewing, you name it. If it's a hobby and there's stuff to buy for it, the temptation is there.
It's easy to justify purchases to support self-sufficiency or homesteading or whatever you want to call it and feel like it's different than buying the latest mascara or hippest handbag. But it's not. It's still buying stuff you probably don't really need. In other words, you could probably make do with other things you already have or can share with others.
In the past I've run Buy Nothing Challenges where those that participated in the challenge pledged to not buy anything new beyond the essentials. It's a great lesson in being mindful of what's in your shopping cart. Before you head to the checkout, you run through a mental scan of "do I need this" for each item you're about to purchase. It's helpful to keep unneeded things out of your cart, but it's also easy to fall out of the habit.
I know I did. Or, at the very least, I managed to justify new purchases because it had some ulterior usage - a new compost bin here, a fancy gardening pot there. Stockpiling like a little squirrel.
In any case, even if you are mindful of your purchases and only buy things that are "useful" for your home or your projects or whatever, do you still feel like you are overwhelmed by stuff? Do you wish you could downsize and reduce the amount of material objects in your life?
