I'm an owl.
And there're times when my owl instincts kick in and force me to reevaluate why i'm in a job that requires me to wake up at 6am in the morning when my optimum time for working is at night.
It's times like this that I read up on articles like this. Comforting articles which affirm me on my existence, but does nothing to help. hahaha.
Unless I change my job, I'd not be able to listen to my circadian rhythm. lol
