Interesting. The manner in which I found MMM is not listed as one of the choices in your poll.
Having come off a severe run of unbridled panic attacks, chronic insomnia, and relentless fear and anxiety over money, I decided to take a pro-active self help approach to curing my mental illness. One, of many steps, in that process involved a google search looking for ways to stop living paycheck to paycheck, which of course turned up MMM in the search results. And since that day, I was truly transformed. MMM, along with other measures, to manage fear, stress, and anxiety, have greatly improved my state of mind, joy, and fulfillment. Though, to be honest, mustachianism is not without its own set of trappings.
