You know that rule “shut down all screens” 1 hour before sleep, but there’s always something to watch/to program etc. Have you found the discipline to do it regularly?
How do you deal with the going-out in the evening, if you strive to wake up at that time?
Do you have some interesting/intense routine like running, which was quite common in american movies?
Go to bed reasonably early. The thing to watch/code/play will be there tomorrow. If you want to go out at night, do it on weekends. As for waking up, I’m used to it now (and my alarm clock app makes me solve a math problem to shut up :)) but long ago when I had trouble waking up, I’d put the alarm clock on a table on the other side of the room so I’d have to get up and walk over to shut it off. By the time that was done, blood is flowing and I’m awake.
