For many of us, the word "ritual" has a lot of weighty significance to it. A religious ceremony, an unshakeable family tradition, or hallowed cultural rite might come to mind.

But according to Harvard Business School professor Michael Norton, rituals needn't be age-old practices imbued with meaning. Instead, we can and should create our own, out of small but emotionally powerful acts. Even drinking the same tea from a beloved mug every day can have the power to boost our well-being.
