I love your way of explaining things. I struggle for a year trying to wake up at 5 o'clock. I never was able to do it for successive 3 nights. Then, I understand that humans are different. There are no unique rules to manage your life. Everyone is unique, so you need to organize your day depending on your personality. For me, I stop trying to wake up early, however, I work more hours in the night. and this makes me more productive.
Finally, there are many ways to succeed in life, everyone needs to choose the one which is adapted to his life and personality.
