The lady knows what she’s talking about!
In my house, we do something similar; we give our items to a friend who holds garage sales, part of the profits is donated to community charity.
This way, we support a local business and charity at the same time. At first, it's difficult, especially for the ladies in my house; they found it hard, but it’s a very liberating practice. Letting go of material things teaches a lot. It’s something so simple yet so challenging that once you get used to it, it feels like a small victory. In a few months, you’ll see it becomes a habit 😉
