The idea that disorganization is the result of insufficient storage space is, in most cases, a misconception. However, having more stuff than you have space for must be handled if you are going to create a working, sustainable organizing system.
So, howdo you handle it?
1. GET RID OF STUFF!! If you haven't read my last post, take a look.
2. Add more storage.
3. Stretch what storage space you do have by making better use of the space.
