I didn't tell my family about the challenge, but I did mention we could have a garage sale if we found enough to get rid of. I am so proud of my girls. Each day they find more and more of their stuff to contribute to the garage sale box.
As much as I was resisting holding a garage sale, I will admit it has been a good motivator for myself. I think once we actually pick a date and start planning, I will see more and more stuff find it's way to the corner of the garage.
