thou shalt not covet

do you ever go through periods where you covet everything and you hate everything you own even though its perfectly fine? i do that with clothes and shoes and things for our house...and our house in general. it's a modest house and it fits our needs which is the counsel we are given by prophets and apostles. we have been greatly blessed but then i go through periods where i think i NEED a 4 bedroom house so I can still have the nursery, the guestroom, and the exercise room instead of having to cram the guest bed, treadmill, elliptical and bike all into one room. what are we supposed to do with all this "stuff" when we have our second child? then I also think i NEED a master bathroom with a HUGE walk in closet. its so hard, there is a new subdivision going in down the street and the homes are so nice but the lots alone are at least 150k. oh how i wish you could grow money sometimes.
