Shopping your home is easy, free, and gives a refreshed feel to your spaces. You don't have to go buy new stuff all the time. Sometimes, your stuff just needs to move around.
We most likely have lots of things already in our homes. By shopping our own stuff, we might find things we forgot about or tend to overlook because they have been in the same place for so long.
There is nothing wrong with purchasing or updating, but we always want to be aware, we want it to be budgeted for, and we want to be intentional with our purchases.
