Sure, it produces cleanliness, but it feels like wasted time to me because any thought I have in the shower is likely to be forgotten by the time I’m dressed and at my desk.
So there’s no point of thinking at all while taking a shower. God forbid I actually have an interesting thought in the shower, because there’s little chance I’ll remember it in 15 minutes. I can listen to the radio and sing along, which lessens the danger of thought. But then I’ve to lug the boom box around.
I need a water-proof writing system in the shower. That would help. I could also check off my to-do list in the shower. Shampoo hair — check. Wash unmentionables — check.
And so on.
