Photograph your bedroom, find the four things keeping you awake

Sleep app gives me a 71 every single night and that's it. Took a photo from my bedroom door, circled four spots in the result: those tiny blue router lights, the gap in the curtains, my phone charging right by my head, and that clock bright enough to read by. All stuff I stare at daily and never actually notice. Taped over two of the lights that same night. Actually worked.
