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 concur with you, but I’d phrase it in a different way: if your budget is $200 for a bike, you should be shopping for a used bike-shop/reputable-brand bike on Craigslist or whatever.
Also, agreed about fixies, except that switching the flip-flop hub to single-speed mode and adding brakes makes it fine.
