I'm going to extend my comment. I've been reading James Altucher's books like "Choose Yourself" and his blog. Altucher's philosophy is somewhat similar, except he focuses on tapping into your creative mind and finding unique ways to supplement your income to the point that you're not necessarily retired, but doing what you love. The goal then is not necessarily to retire, but to just get to a point where you are working for yourself and supplementing that with existing savings + a frugal lifestyle. That's basically what MMM/Pete is doing now with his blog. That is, I believe, how a welder/car mechanic/McDonald's employee can retire early.
