Wear lipstick more (I don't go out enough to save it for special occasions).

Make a fancy dinner once a week, starting with some recipes from Ad Hoc at Home.
Cook something substantial twice a month so I will have leftovers for lunch. This is the pulled pork I made two weeks ago. It fed me, my roommate, and my boyfriend for a week.
Always have on hand a book for leisure reading.
Take pictures.
And relax!
