I am focusing on the "blow my mind" part, rather than the "beautiful" part of your question, but I am certain many philosophically-minded people would consider the following "beautiful".
Peter Singer's argument in "Famine, Affluence, and Morality (1972)" that you and most everyone you know are probably immoral or evil and you don't even realize it. It really affected my ideas of how to strive to live.
Here is a good video explaining the idea in detail, worth 30m of your time.
At least twice a day, usually three times a day, but I have "reasons".
After not taking really good care of my teeth for too many years, I needed surgery. I recovered completely and kept my teeth, but was clearly given the message that if I want to keep my teeth I need to be diligent about their care. I've lived long enough to understand the value of having a working, pain-free set of a choppers. So, I complied.
Once I had recovered from the surgery and infection, it became clear I needed braces, so my dentist suggested Invisaligns. These have the "benefit" of making you brush your teeth every time you take them off (to eat, to drink anything staining) and put them back on. I have to wear my braces 22 hours a day to comply with the treatment.
My normal routine is to get up in the morning, take my braces off, have as much espresso as I want and maybe some yogurt, then brush my teeth with a stain-removing paste (Arm and Hammer Peroxicare) and put my braces back in. Then at lunch I pop out the braces, eat, brush my teeth (Peroxicare), then pop my braces back in until dinner. Dinner, rinse repeat, but then I use a Crest Gum Detoxify before popping the braces back in before bed as part of my ongoing post-surgical routine.
I also use a water flosser at least once a day.
My teeth and gums are really healthy now and I intend to keep them that way.
