As I come to the end of my advice and send you off into the world, I have an alternative way for you to stay on the straight and narrow: periodically watch Groundhog Day. It was made long ago, in 1993, but it's still smart and funny, the chemistry between the stars (Bill Murray and Andie MacDowell) is terrific, and it has a happy ending. Groundhog Day is also a profound moral fable that deals with the most fundamental issues of virtue and happiness.
