A fellow Mustachian and I were discussing this article (the comments) this morning, and he (he's a psychologist) was talking about how they all exhibit "victim thinking". For example:
"There is NO WAY I could possible save any money because I was taken advantage of by the MAN, banks are evil and don't let me get ahead, I had kids, my car is too expensive, I didn't get an education, my energy costs are JUST TOO HIGH, etc, etc. It's not possible and it's all somebody else's fault."
Mustachians, by and large, approach it with a sense of control and purpose: "I wonder how much energy I spend on XYZ? I will objectively measure it and develop a set of data points, then I will analyze the data and make incremental cuts or changes in the way I do things and affect positive change. I will repeat this process until I've shaped my life and spending into what I want it to be and then I will achieve my goals."
Mustachians are the Captains, with apologies to William Ernest Henley. :-)
