We love to play. To playfully try things out that make us curious. Whether these things want to be played with or not. Because the challenge is part of the game. Just like in real life. Though we should clarify one thing, as a cognitive aid to help those holding intellectually insecure or stubborn views to better understand the matter at hand: If you take an easy-going perspective, then a playful attitude and serious demeanor never have to exclude each other. On the contrary. In life, you have to improvise. Wikipedia defines “play” as a range of activities done for recreational pleasure and enjoyment. Often seen as frivolous, play can be intently focused on an objective, particularly when it is structured and goal-oriented, as in a game. This is what we call “flow”.
