I don't think being a morning person has much to do with loving/hating to wake up early. It's more about how easy it's for you to get enough sleep if you have to wake up early every morning. I'm definitely not a morning person, but I love waking up early (ideally a bit before sunrise). Unfortunately my circadian rhythm is always creeping forward. Whenever there is something special (like a trip across multiple time zones) that allows me to reset the rhythm, I get a couple of weeks of early mornings. But eventually I'm back at balancing between sleeping late and not getting enough sleep, because I fall asleep a little bit later every night. That "taking care of themselves" sounds much like "listening to your body" as a cure to obesity. Taking care of themselves is precisely what makes some people sleep late.
