I recently started a job that requires me to wake up at 5:30am. I thought "no big deal, I'll just adjust my sleep schedule."
I was, however, wrong. It is miserably difficult and after just a week I feel like tapping out. And yet, I know plenty of people on the world have spent/will spend most of their lives waking up in the early hours of the morning every day with no issue. How the hell do they do it? #conversation source
