Holding grudges keeps your body in fight-or-flight mode, damaging your health over time. Try this nightly routine: visualize each person who upset you, look them in the eyes, and say "I forgive you. Please forgive me too." It's based on the Hawaiian practice Ho'oponopono.

The person who bullied you in school, the lover who dumped you for somebody else, the boss who promoted your peer instead of you— the list of people you hold grudges against could get long and ugly when you think about it. The negative emotions that come with holding on to a grudge are in fact a stress response. Just thinking about the event may send your body into fight-or-flight mode, a survival mechanism that forces you to stand up and fight or run for the hills when faced with a threat. When the threat is imminent, this reaction is essential to your survival. But when the threat is ancient history, holding on to that stress wreaks havoc on your body and can have devastating health consequences over time. Holding on to a grudge means you're holding on to stress, and emotionally intelligent people know to avoid this at all costs. Letting go of a grudge not only makes you feel better now, but can also improve your health. The fact is that you cannot please everyone. Inevitably, you will have an encounter with one or more people who rub you the wrong way. If you have any lingering emotions from that encounter, get into the habit of keeping a list of what negative encounters you experienced during the day, so you can take care of that at night. In the evening, before you go to bed, review your list and those people who were involved. Close your eyes and imagine that person facing you. Look them in the eyes and say, "I forgive you. Please forgive me too." This process stems from the Hawaiian practice called Ho'oponopono. There are meditations available that can guide you through the process simply by Googling Ho'oponopono. Just make sure the spelling is right. Ho'oponopono helps you imagine that you are forgiving the person you are holding a grudge against. And that person forgiving you too. This process restores harmony within yourself by eliminating the stress and resentment you have been directing at that person.
