De-cluttered...somewhat

We just finished two hours of cleaning out our storage room. It has been my goal to never have things in my house that I never use so I need to frequently clean things out to meet that goal. Things have gotten piled up in this first year of marriage and I thought it was time for a clean sweep. I can only imagine how many things can accumulate after years of this. It has become an impossible tasks to get rid of everything we don't use since some things have sentimental value. How long to we have to keep these things before we really don't care about them anymore? I feel like they are still cluttering up the place. I am really good at throwing things away and actual enjoy it. When I hear of people that hoard things and it takes over their house, I practically have and anxiety attack for them. I think I have decided that it's okay to store a few things that I'll never use again as long as it's not taking up valuable storage space for useful items. I am patiently awaiting my Space Bags to arrive. I ordered them online and I have piles of things ready to be vacuum sealed for much more storage space. As soon as that is taken care of, I will really feel that sense of accomplishment that comes with cleaning and organizing a very cluttered area.
