Dangle a Week-Carrot.
Look, the world of happy moments doesn't have to end just because Monday must be spent wearing real clothes. Happiness doyenne Gretchen Rubin, creator of the Happiness Project
and author of bestsellers Happier at Home
and The Happiness Project
, says, "Give yourself a reason to anticipate the coming week: Plan lunch with a friend, or a movie outing, or a trip to an office-supply store—or am I the only one who loves to go to office-supply stores?—and when the Sunday blues hit, remind yourself of everything fun that will happen."
