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?
£500 - £1000 is the sweet spot for electric guitars. Anything much higher than that is the exact same guitar, just with extra bling.
Acoustic/classical guitars are a bit different and even though they still suffer diminishing returns, a higher price can be more easily justified.
