One of my clients doesn’t go out with more than three people at a time. She finds that’s her perfect number, at which she can give each person a chance to let the relationship grow but also can compare how she’s feeling with each one. If you go overboard and chat with too many people at once, or constantly fill in your calendar with first dates, you are likely to end up like the person who sampled from the table with twenty-four jams. You’ll try more jams but won’t know which one to buy. The result? A lonely walk home, a bellyache from all that sugar, and dry toast.
