Exercise a lot (and get sunlight exposure) during the day.
Also, never watch movies, read, scroll on a phone, etc in bed. You want your brain to 100% associate being in the bed with sleeping, as soon as it happens

(edit: also, minimizing light exposure in the last couple of hours of your day is good)
