Marriage counsellor Janet Tanzer of Toronto is a firm believer in the power of dating to shake up the same old, same old. Tanzer explains that passion thrives on mystery. A lasting marriage, on the other hand, owes a lot to security and predictability. But you can make a conscious effort to recapture the excitement of your courting days. Dating can jolt you out of your routine. "It's the playfulness that matters," says Tanzer. "If you focus on surprise, passion will follow."
