For me showering means standing in a windowless room staring at a blank wall for 20 minutes (I get lost in my thoughts). Also there are several steps and I have to think about each of them.
This means that I only end up showering when my fear of coming across as dirty becomes bigger than the dread of being bored.
What do you do?
Think up an entire story from start to finish. Before you know it you’re done.
