This book changed my life.
It showed me one doesn't have to follow the route of college, then graduation, then job for life. I bought this book, then worked for three years in London, Spain, and Cairo in the late 1980s and early 1990s. I supported myself and even managed to save money.
While personally enriching, my experiences have impressed -- bar none -- every employer with whom I have interviewed over the past seven years.
Had I not taken time off, I'd be like many other adults who regret not taking advantage of their youth and lack of committments to explore the world and themselves.
If you have any desire to explore, do yourself a favor -- buy the book, then buy your plane ticket.
