The ability to laugh, play, and have fun with others not only makes life more enjoyable but also helps you solve problems, connect with others, and be more creative. People who incorporate humor and play into their daily lives find that it renews them and all of their relationships.
Life brings challenges that can either get the best of you or become playthings for your imagination. When you “become the problem” and take yourself too seriously, it can be hard to think outside the box and find new solutions. But when you play with the problem, you can often transform it into an opportunity for creative learning.
Playing with problems seems to come naturally to children. When they are confused or afraid, they make their problems into a game, giving them a sense of control and an opportunity to experiment with new solutions. Interacting with others in playful ways helps you retain this creative ability.
Here are two examples of people who took everyday problems and turned them around through laughter and play:
As laughter, humor, and play become an integrated part of your life, your creativity will flourish and new discoveries for playing with friends, coworkers, acquaintances, and loved ones will occur to you daily. Humor takes you to a higher place where you can view the world from a more relaxed, positive, creative, joyful, and balanced perspective.
