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?
This is great advice for anyone looking to buy used and not new. Don’t buy someone else’s problems from Craigslist. If you can, buy something from a reputable source that includes a warranty.
