I agree and yes I do sometimes bill my shower time. That's where the best work gets done after all

But I think it's much deeper than that. It's the basic truth that creativity emerges from a still mind. First you spend hours obsessing in front of the screen seemingly achieving nothing. Later you seemingly do nothing and solve the hardest problems.

It's an excellent practice to take breaks where you do nothing. Pretend to be a smoker and step out for a smoking break every hour or so.
