"The 4-Hour Workweek" by Timothy Ferriss, a book advocating for a "New Rich" lifestyle focused on time and location freedom rather than traditional retirement. The excerpts highlight the book's core principles—Definition, Elimination, Automation, and Liberation (D-E-A-L)—through a combination of testimonials, FAQs, and Ferriss's personal experiences. It encourages readers to outsource tasks, optimize productivity using concepts like the 80/20 Principle and Parkinson's Law, and embrace "mini-retirements" as an alternative to conventional vacations. The text also includes practical tools, resources, and case studies to guide individuals in designing a life with more leisure and purpose.
