As an adult, I can confirm that it later becomes the exact opposite. I have no problem jumping out of bed at 5:30am for another wonderful 12 (possibly more) hours of work. :D
I don't want to think I've gone quite that far, I still remember a time when 2am was a normal thing in my life. Right now I shall call my ability to easily awake before 6am begrudging acceptance, that is two levels or so below a full embrace.
You spelled "embrace" waaaaay wrong.
