Honestly, without any actual context given, none of us can really tell what keeps you awake. What do you do before going to bed? When do you wake up, and when do you go to sleep?
The most common problem is that people can't sleep after using their computer or phone. Typically, you should not be looking at any kind of screen 30 minutes to an hour before going to sleep, as they emit what is known as "blue light". Basically, your monitor/laptop, TV screen, your smartphone, and even the sun (though I doubt you'll be looking at that before going to sleep) emit this "blue light". Among other things, "blue light" boosts alertness, and (at night) disrupts the circadian rhythm, which is the body's natural sleep and wake cycle. Obviously, this is no good if you actually want to sleep.
I personally find it easier to fall asleep with some quiet background noise, be it of people talking like a podcast or an audio book, or some music, so you can try that out as well.
