How can you best savor good feelings and dismiss bad ones?

For positive emotional experiences, don’t try to explain them. For negative emotional experience, definitely explain them. Analyzing feelings reduces emotion.

Moore researches how word-of-mouth stories affect our feelings about our experiences, and she has found that our feelings change when we share them. She says that when the storyteller analyzes or thinks about an emotional experience like a family vacation, it reduces the emotions, positive or negative, about the event. However, she notes that for practical experiences, such as buying and using a USB stick, analyzing and thinking more about the experience will amplify our feelings about it, be they positive or negative.
