The 4-Hour Workweek: Is it really possible?

I'm halfway through listening to the audio book version of The 4-Hour Workweek by Timothy Ferris. While many of his strategies for reducing non-productive (i.e. non-profitable) time and increasing leisure time and achieving goals sound great, do they really work? Well, he's done it himself, though not without challenges. I don't know that I can do them all, but I will be putting several of his strategies into practice and reporting back here whether they worked for me (e.g. blogging from Tahiti) or not (e.g. get fired). This should be interesting.
