When did you last let go and play?
George Bernard Shaw said, "We don't stop playing because we grow old; we grow old because we stop playing." Though we mostly need to let go of being childish, we can continue positive
childlike traits as we grow up. Children tend to laugh more, to take life lightly, to be completely in the moment, and to be silly and spontaneous with what comes up, especially while they play. We've all met people who age playfully, and others who seem to lose touch with their inner child.
Play involves engaging the imagination and trying new things just for the fun of what might happen. The scientific process is similar, starting with a question and thinking and imagining what might happen, then experimenting and making observations to find out. The creative process, too, is about getting ideas, and exploring different ways to implement them. We try one thing, see what happens, and then try another till we create what we want. As long as we don't let our inner critic in, it can be almost like play.
Playfulness is one of the most critical attitudes for innovation. To be more playful, we can play games, play with our children and families, and play with ideas. We can play while we work, play while we create, and play while we exercise and move our bodies. We can almost make a game out of life, stopping to notice humor that feels stitched into our cosmos.
There's plenty of time for being serious, but as you remember to get out of your thinking/analyzing brain and have some fun each day, see how that expands your creativity.
