Miraculously enough, my wife is coming along. Now, to be sure "Mustachian" is a relative term, IMHO. I mean, there's no way in hell I want to or ever will live on a $25K annual household budget. But, as far as cutting out unnecessary costs, maximizing pleasure by purchasing those things that bring lasting happiness, avoiding debt, using credit cards properly to reap rewards, and saving aggressively for tomorrow -- those things we can all get down with, regardless of income level. My wife, a former serial shopper and credit card addict, has pretty much done a 180. She still buys really stupid shit from time to time, but she's really begun to see that you can't live just for today. Oddly enough though, it wasn't solely my doing -- rather, recently, she's begun to clue in to the financial woes of her friends, and she's been pretty astounded to learn how stretched many of them are despite appearances. Example: I direct deposit money each payday from my check to a joint account we use for paying the mortgage and saving. I had no idea really how much was going to what, and so she fairly astounded me just yesterday when I asked her and she told me how much was going to savings each month. Suffice it to say, it was more than double what I thought was going in! That's my girl!
