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 think when people say to but high quality items, they mean to spend what they’re worth. Getting the most expensive thing doesn’t really guarantee a quality item, but cheaping out makes it much more likely that you’ll end up with something lackluster. Plus, something like sleep can be fairly complicated and is connected to your habits, what you’ve eaten, or schedule, etc., so expecting a single change (pillow) to make a huge difference may not be realistic.
You’re usually fine using a cheap item. If you use it enough to break it, then you need a quality item.
