I like his style, and unlike many others, he actually took the plunge and stopped working at 30... He's pretty US focused though, and it does seem that you have a better chance of retiring young there than pretty much anywhere else. High income, good investment vehicles, low tax and the ability to keep costs very low.
I like the idea of retiring young, not from work, but from my desk job. I quite like the idea of getting a paycheck, but I like the idea of deciding for myself how it's done even more. While I could pack up the bags and "head to Portugal" when my current contract ends in December, I have other plans (taking my boy around the world on a catamaran when he finishes school) so I'll need a pretty decent sized stash, and a contingency for the worst case scenario. Realistically I'll hang up the tie sometime during my 43rd year on this planet...
