There’s something about showering that tends to spawn new ideas which may not occur otherwise. And the frequency with which this occurs seems to suggest that perhaps the occurrence isn’t merely happenstance, but instead a decent model for what has been called “creative pause” – the shift from being fully engaged in a creative activity to being passively engaged, or the shift to being disengaged altogether.
You may or may not be able to replicate this “creative pause”, but one thing is certain – a shower is the place for the most awesome epiphanies. I am constantly surprised by the quality and elegance of solutions that strike me under the water spray.
