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?
Yes, in light of keeping the new vehicle for its entire "life" the depreciation argument falls fairly flat. It is more meant for the "average" person who keeps a car for three years or thereabouts. I cannot imagine investing that much money flippantly. I take the time to research what I want and mean to keep my auto for a long time. That said, I prefer a solid used car over new because it has depreciated to a more fair value. I've done both and not been displeased with either choice. Except for one BMW...
But even if you drive the car into the ground there is still an associated cost per year as a result of buying the vehicle.
