Good deal!

The biggest obstacle that I used to have with falling asleep was the issue of racing thoughts. Not bringing my daytime concerns to bed with me was a big step forward here. If stray thoughts come up to bother you, just acknowledge them, gently set them aside, and just lose yourself in your meditative breathing once again.

Another kicker for me is keeping the room as dark as possible. If my room's not black as a cave, my sleep quality is noticeably worse. Extraneous light will affect your melatonin levels and create extra headwinds for you to overcome when falling asleep.

Anyway, just a few pointers on stuff I had to work past in order to get better at falling asleep.
