I know that when I'm tired and done for the day, I'm good to go to bed. Flossing is a maintenance chore that's needed only because our teeth aren't good enough (and can't be made good enough, yet) to not need it.

If I were in that situation, I'd prefer to stop driving to work (by e.g. going remote, or relocating), but I'd also want to have an uninterrupted time for being with my thoughts anyway, perhaps explicitly scheduled and negotiated with my S.O.
Etc. Now, I'm not really criticizing you as much as I envy you - my life would be happier if I could hack my brain to see the tedium as something worthwhile, instead of doing my best to minimize its amount and impact on my life.
The afternoon commute with the traffic jams, buses packed with students, noise... nope, never missed that.
I disagree. Those are simple rituals that makes life enjoyable too. For instance, I know that after flossing, I'm good to go to bed. Or I know when I'm driving my car that I won't get interrupted and I can wander with my thoughts.
