Go to lunch … with a few restrictions. You have to go somewhere that is pleasant and requires you to wear reasonable clothes. You have to eat something sensible; you cannot go out with your food-junkie buddies or a hard-drinking crowd. Instead, venture into civilized society and pretend you fit in. If there is no one at work or from your friends to go with you, enlist the aid of your assistant. The point is, pretend to be happy, even if your emotions have not caught up yet.
