It's step by Step; room by room; it's difficult and easy at the same time. It's your stuff and you don't want to throw it all away. You don't have to! It just needs to be organized in a way you're comfortable with! I do this all the time! You've got someone to do it with. I've got your back!
If you're selling, it's imperative. You have to do this. If you're busy and just don't have the time and the basement, the kids rooms, the closets....are calling you in the middle of the night... it's time to get busy.
You'll feel freed up, less burdened. I guarantee it! It's transformational.
Organizing your space...will change your life.
