I am a person that tends to see the mess and inside I am freaking out. I don't where to start how it got like this and how to keep it neater. Flylady helps with the routines she has and as you start out you start in baby steps. You do 15 minutes at a time. Not to overwhelm yourself.
Fly Lady also has books. One on cleaning house the other on body clutter.
I hope this helps someone else. As it has at times helped me.:-)
