Proven aids to falling asleep faster:
Sleep alone; a bed partner will disturb with movements, snoring, talking, and may distract with other bedroom activities.
Avoid backlit or self-lit displays (computer, cell phone/tablet, TV, etc.) for an hour before bedtime.
Eliminate caffeine (coffee, tea, sodas) for at least the last six hours before bedtime; preferably, completely quit using caffeine.
Don't smoke immediately before bed (and especially don't smoke in bed; this is a serious hazard of dying in a fire if you should fall asleep with a lit cigarette in hand or mouth).
Make the bedroom as dark as is practical.
Use a noise generator or recording of surf, rain, or forest sounds (whatever you find restful) to cover outside sound (traffic, others in the house, etc.).
Go to bed at the same time every night -- weeknights and weekends -- and get up the same time every day, even if you're not fully rested (this resets your daily rhythm to the schedule you need for workdays; sleeping in on the weekend disrupts that rhythm). Allow at least seven hours, preferably eight, for sleep -- from light out (if you read or do other things in bed) until your alarm time.
Note that experts say that if you take less than twenty minutes to fall asleep in a dark room without distractions, you are probably sleep deprived; don't put too much emphasis on trying to get to sleep in ten minutes. On the other hand, if you're doing all these things and still can't get to sleep in under an hour, and still exhibit symptoms of sleep deprivation (tendency to fall asleep during the day without constant stimulus is high on the list), you should get your doctor to refer you to a sleep specialist; you may have a sleep disorder (insomnia, sleep apnea, or something less common).
None of this is really a "life hack", it's all just good practice everyone in our habitually sleep-deprived society should follow (though many/most of us can dispense with some of these if they aren't causing trouble).
