Timothy Ferris' The Four Hour Workweek is a book devoted to people who do not want to spend the rest of their lives working in their cubicles. It makes a case for automating your cashflow so that you are no longer dependent on your job. It introduces the concept of freedom as one where you are both free from money and time pressures. Just having a great deal of money is not enough to be really rich, according to Ferris. You also need to have a lot of time to do all the things your heart desires.
Ferris makes a very compelling case for setting up some business major components of which can be outsourced to generate the free cash flow. He then goes into how to setup a "outsourced" business and life.
The book in this stage becomes a bit "silly" at times. Ferris, when he wrote this book was a 30-something person without a family. So, going away to foreign countries and staying extended periods may be possible for him but is practically not possible for most people.
What is important to learn from this book though is that there are a lot of things in life (and business) that you can really outsource and not feel any negative consequences at all. In fact, it would help get rid of a lot of unwanted "activity" - stuff we do just for the sake of it.
Overall, a good book to read.
