Project Happiness
Apartment Therapy has some great ideas about how to make yourself happier, specifically happier in your home.  A few of them I currently already do on a daily basis - make my bed, display sentimental items around my home, etc.  That being said, there are a few on the list that sometimes fall by the wayside and, when left neglected, they create a subconscious anxiety within me. It is important to recognize how the small things create either stress or relief in your life. Check it out, even just to remind yourself.
