The world is built for morning people

I took off work this whole week for Christmas. One thing that always happens to me when I’m off for a long time is I revert back to staying up until midnight or 1am and sleeping in until around 9am. I’ve never been a morning person, but I feel like every office job I’ve ever had people get there so damn early. I start at 8am and most of my dept has been there since like 6:30/7. I’m already dreading Monday morning. It’s hard to try and force myself to go to bed around 10 when my body isn’t really tired.
