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 early. Easiest trick in the world.
You can also drink a bit of fluids before bed so your body naturally wakes up fairly early, the old Native American trick.
Weak bladders beware, with this one trick you will wake up early. Not the way you want.
