Have fun, because life was meant to be enjoyed.
Have fun without keeping score if you’re having more fun than someone else, because that’s tinged with the pressure of competition. And competition may spike you with a jolt of adrenaline, but ultimately it feels more like work, which has it’s value, but isn’t purely fun.
Have fun for the sake of having fun, and not as a way to avoid something serious, because that’s tinged with guilt. And guilt is a real fun-eater.
Have fun because it brings joy to your life, and bringing joy to your life adds to the joy of the world. And the world needs more joy.
But no pressure. Because pressure isn’t exactly fun.
