I am not a morning person to make the understatement of the year. My preferred sleep schedule is 4 am to noon or 1 pm (that is what I did today because it is a weekend). I finally got a job 6 years ago with sensible hours. I am on call most of the time but only have to be on-site by 10 am and it is 28 miles away. Thanks to Eisenhower, I can wake up at 9:20 am, take a shower, dress and be there exactly on time almost every time.
I suffered through early schedules all through high school and many jobs and I am simply not doing it again. It makes me physically ill over time and I have never adjusted to it well. That isn’t a failure of will on my part. It is just the way my body works.
I am not an activist type in general but that is my one true cause - discrimination against those with alternate biological clocks. I am awake as many hours a day as anyone else but it is offset. I find it extremely difficult if not impossible to fall asleep before 1 am let alone 10 or 11 pm like many people do.
It takes all types though. If you want someone to show up at 7am every day to do a routine job, I am not your guy. However, I am the person that you can call at midnight to take care of something complicated because that is when I am at my most alert.
There is nothing special about the early morning hours as opposed to the very late night. Both of them give you quiet time to do things when there aren’t many other people are around. My body just strongly prefers the latter.
