* You will be in control!
There is nothing worse than feeling out of control in your own space.
* You will have more time!
Think of all the time you spend looking for stuff you put "some place safe".
* You will have more space!
When everything is where it belongs you have more space for other stuff.
* You will have more money!
How many times do you buy something that you have because you can't find the first one?
* You will impress your friends, family and neighbors!
Ok, this may not work on everyone, but an organized room does make a good impression.
