This movie is worth being watched over and over again, it never gets boring, and I don't normally like rewatching movies, they are not as powerful the second time, but this one still keeps its essence.
I feel you; I try to spend as few money as possible not because I really need to do it but because it's the lifestyle I want to follow. I haven't heard about that specific rule, but I did hear about exercises where for a short while you are doing something very weird so you stop carrying in time, it's the same thing just that I had no idea how it's called.
Ok, I'll put that movie on my list and see about it in the future. ;)
