I'm not sure this is entirely true. I understand the logic, but it's important to note that theres still a net positive in the more subjective ideas of "greeting the day" and finding yourself in a more calculated, healthy routine. Waking up early in the morning, if surrounded by many who also do the same, also lends itself to being surrounded by a group of typically disciplined, motivated and honest people, where little downside can be seen. All of this is deeply subjective, but I think there's some logic to it.
