This might be a longshot. I am looking for a quote Mr. Money Mustache wrote in one of his blog posts. I believe he was discussing fitting in while being mustachian, and the key is to have neither the most expensive or least expensive of something.
From my memory, the exact quote was something along the lines of:
"Most expensive purchases boil down to purely fantasy ideas of how that item will change a person's life compared to the less expensive choice."
Any help on finding this blog post would be greatly appreciated. I want to share it with a friend.
