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?
I got a square one
I was sleeping on a tiny rectangular memory foam couch pillow for months before I finally got my new awesome pillow, because the tiny pillow was much better than the shitty full size pillows
