I'm a frugal person. I live beneath my means (and more), I make things last as long as they can, I buy mindfully and I look for new and better ways to do things. However, I don't live simply and I am certainly not a minimalist. For many people, these things seem to go hand in hand. But for me, being frugal is being able to live as bountifully as possible on as little income as possible.
A minimalist will have five tops in their closet, one for each day of the week. I on the other hand will have ten tops, all bought at yard sales and thrift stores, for half the price of the single shirt. These are generalizations, but you see the point. My goal is to have the things, the comfort if you will, for minimal expense. I'm willing to expend effort as needed to meet that goal.
One year, when my daughter was six, I was perusing a neighborhood yard sale. A mother with daughters who must have been seven or so had three large blankets full of size 6X clothes. Many of them were Sears mix and match styles (what us old folk had before garanamals and gymboree). She was more interested in getting rid of them than the cost, so for twenty bucks I got a huge deal. My child had so many clothes, I could wait two weeks or more to do her laundry!! A minimalist would clean out most of those clothes. but I got the clothes for a song, I had a place to put them, and she wore them.
Also, in my opinion, before one eliminates an item or items, one should consider the replacement cost. Now that I'm a widow with one at home child, I use a small crock pot. In fact, that's all I used for a year. I seriously considered eliminating my large pot. However, in the past couple of weeks I have done two potlucks and had a request to make a large Boston butt. All of these situations require a large pot. I cannot tell you how thankful I am that I kept my seven quart crock pot. If I'd followed the six month rule it would be gone, and there I would have been.
Now, I'm not advocating hoarding or keeping items one doesn't have room for. I've recently decided that I'm not buying any more bookshelves, and that means some books must go. I acknowledge that one needs a place for everything and that one needs to be able to find everything. Beyond that though, we each make our personal decisions. Personally, I'll be the gal with the dishes for Christmas, Easter, summer and fall (mostly bought at yard sales or on deep discount of course)!
