Making the Home a Happy Place

Do you ever have one of those days that everything seems to need you to make the decision?  How about a week / month  / year like that?  I have had a few days in a row but my wife is having a year like that.  It sucks both life and happiness out of a person.  Am considering what to do to make her have a smile.  I usually buy her flowers (about every other month and guys it is worth it, and do it for no reason - they don't expect it and the love it).  Any ideas?  I think I need something new.
