more - less

to add is easier to subtract - ie to add something to an already existing routine and make this a new routine with an added item is easier than to subtract something from a routine and make the routine with the subtracted item a new routine.

say, you are used to recite the prayer "Lord Jesus,...... and my mother, my family.... amen."

since mother has passed away, would want to take her out of the prayer. but it would not be that easy. when the prayer is routine, then the subconsciousness takes over, unless you make a very conscious effort to recite the prayer with mother's name out, else you would end up with mentioning mother again and again.....

why?

subconsciousnes is like dark energy, it makes up most of our consciousness.
