I value my sleep time, which is why I'm not going to bed earlier than when I actually feel like it, as it usually results in hours spent on useless disorganized thinking about everything and not sleeping much.
That “useless disorganised thinking” is very important. It’s the first time all day your brain has had a chance to ponder things and not being bombarded with constant stimulus.
No, this is not the welcome kind of "disorganized thinking" you get under a long shower. This is the useless kind that prevents you from sleeping and seems to always have some terrible faux pas from 15 years ago prepared to randomly remind you about.
