Start a laughter memory journal to record your laughter memories. Write down your laughter memory at the end of the day or when the memory is fresh. Having these stories will help prime your laughter pump when you need a lift.
Here are several suggestions for locating laughter memories. Share funny articles or comic strips with others who like to laugh. You can also seek out "laughter yoga" clubs, where movement and laughter are combined to create daily, communal laughter memories. Another useful way to create a laughter memory is to simply recall a hilarious film or TV show. Make a list of your top-five funny films and watch them again. You can also combine a problem you are experiencing with laughter. By doing this, you are integrating two apparent opposites and creating an entirely new mind-body feeling state. Since no situation is completely bad, this laughter memory can help you develop a broader and more humorous perspective on almost anything.
At the end of the week, look over your journal and review your laughter memories.— Donald Altman in The Joy Compass: 8 Ways to Find Lasting Happiness, Gratitude & Optimism in the Present Moment
