I found this book absolutely inspiring. It's a collection of travel quotes, and thoughts about travel. An analysis of what travel means and its effects on the traveler, but also how anyone sees the world in such a different way and how travel has a different meaning in each one of us.
Paul Thoreau also brings us numerous historical travel writers, so lots of inspirations for the next reading choice.
"Travel is at its most rewarding when it ceases to be about your reaching a destination and becomes an indistinguishable form of living your life." Paul Theroux
