A couple of reasons for it.

I was wasting my time in evenings on useless stuff and was mentally drained to do any productive work.

I need to change the type of industry I work in, so I feel the solid block of time in the morning with a fresh mind is the best time to learn new skills.

Also, I am single and got divorced last year. I found myself wasting time, contemplating mundane things, reading psychology forums in evenings. It was not helping me get out of the hole I was in. So I changed my schedule.

Really interesting. I find I'm most productive in the evenings. Do you happen to agree with the research suggesting people have natural inclinations towards more/less sleep and different productivity rhythms during the day? It seems like reading between the lines you've augmented your sleep patterns from what they normally are.

I think the sleep and productivity times vary with age, food, and stress levels. I used to be a late nighter almost all of my teen life into the early 20s. But have now become early(rather super early) riser.

As expected light plays a huge role in altering sleep cycles. All my devices go into blue light mode around 5:30 pm, and same with Hue lights at home. And the lights turn on to 6500K ~30 mins before my alarm goes off. If for some reason my lights do no turn on I still find in hard to wake-up at 2 just with an alarm.

As for food, I've noticed on days my diet is heavy in red meat, and fats I tend to sleep longer.
