Pick a “must get out of bed before this” time. For me it’s 9am. Pick a time 2-3 hours before that. For me, best was 6:30am Go to bed and be asleep at least 6 hours prior to the first alarm. I often can’t do this but I try.

your “trick” is to intentionally rob yourself of 1/3 of your available sleep time? that is the worst trick in the history of tricks, ever.
