I have a weakness, one that I have passed down to my children. Books. I have to have them. It might be a problem. Last I checked I had over 100 downloaded to my iPad. In the house well lets not talk about that. Ok lets talk. If I was able I would have stacks everywhere, but alas I can not. You see you have to have this thing called furniture and a place to store food. Most people would probably like to walk. Trust me unchecked I would probably become a house on hoarders, just minus the garbage and dead cats.
My solution: I have restricted myself to one shelf. This helps by making me get rid of books I don't need and will probably never read. When I am done with a book I hold on to it for a bit then think will I read this again? If not off it goes. Off to ebay or donated to the library. Better than collecting dust around here.
One shelf may sound like a small amount of room but really you can fit a lot on it. That also does not mean that I don't have them stashed in my car and other rooms in the house. Just trying to not end up on hoarders one day.
