The first step to getting organized is to toss or recycle useless stuff such as: Wire dry-cleaner hangers, socks with no match, old florists’ vases, broken umbrellas, last year’s holiday cards, old makeup, used notebooks, dried-up cans of paint, pens that are out of ink, dead batteries, and old spices, etc. 

Step two is to set aside everything you are going to donate OR sell. Once you hit that sweet spot after trashing, donating and selling everything in your house you no longer need in your house, THEN we can talk about what to move into your storage unit to leave behind  O N L Y  what we need to stage your home while you still live there.  

Be ruthless. I promise you won't miss anything. Good luck!!!!!
