The best I've ever found is John Cheese's Cracked articles on the topic which I felt were almost like he was writing from inside of my head.

If someone reads these, please understand that this is how I actually feel/act to this day, even though I make 100k+ a year. For example, I only own two pairs of shoes. My work sneakers, and my "nice" shoes. And I replace my sneakers only when they are completely busted, and I get the cheapest ones on sale I can find. Three pairs of shoes is literally crazy to me, and I feel bad about having 2 pairs of shoes since I never wear the "nice" ones.
