For me it was “buy high quality pillow” because you sleep for one thrid of a day etc. I needed a new pillow anyway so I came to the store and bought the best they had. And it was … ok. Like it’s a fine pillow but my sleeping haven’t improved really, it’s basically the same. So I was disapointed :(
So, which life pro tip disappointed you?
Just buying an expensive pillow won’t necessarily improve your sleep. You need to try out various pillows and find the type that works best for your body and how you sleep.
