Oh, these are some stunning visuals! ^^
Yes, I've also noticed this with myself as well, if I start off the day right, nice and early, the quality of the whole day is just so much better. I'm more focused, more driven, and I actually manage to get things done.

Now I wonder.. it must be something related to brain chemistry, but then it begs the question, what is it that 'breaks' in the brain if I 'oversleep' (and by oversleep I mean anything past 7:00)..?

Hope you have an amazing week ahead! ^^
