Last year I spent a lot of time trying to reduce the clutter in my home. I feel like I did pretty well - when we moved into my house, my office was filled top to bottom with boxes. Now, I have shelving up and my desk and I work there. I purged by selling things, giving things away, giving things to Goodwill. I have never had a storage unit, nor felt like I particularly needed one. After reading this article on Get Rich Slowly, I am glad I never got one.
Do you have a storage facility that you store stuff in and pay for each month? You may want to rethink that decision.
I still have a long way to go in my basement. In fact, I have a whole area filled with toys, clothes, and baby equipment that I am storing until the end of May to sell at a big sale. But little by little, we are getting things out of our house. Now if I can just stop the flow of stuff into the house (especially paper!)!
