I like your idea of trying a new habit a month.  Since it seems to fizzle out, let's try to remind each other.  Want to post the whole year here and we'll try to make a conscious effort to remind each other?  I also want to declutter this January as usual but I don't want that to be my new habit.  My new habit that I will consciously think of every day in January is to try not to put anything on the floor and to remind my family not to do put anything on the floor.  Other than their feet or chair legs!
