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?
Every car I’ve owned has been used. Some are better than others. In general, I’ve had really good luck and have bought some great cars, but some have been money pits. You get better at spotting a good buy, but it’s still possible to get a bad one, it does come down do luck.
