My solution is simple but can work in time....... Start out at home by placing some thing small out of place and let it stay that way for a week with out fixing it, then move up each week with something bigger and let it stay out of place for a week - in time try leaving dirty dishes in the sink for a day or two (or) dirty clothing on the floor, out in the open, for you to see every day but with out you picking it up..... all things are done with Baby Steps.
Good Luck.............
