Zen and the Art of Motorcycle Maintenance

Zen and the Art of Motorcycle Maintenance: An Inquiry Into Values
Robert M. Pirsig

From Amazon:

One of the most important and influential books written in the past half-century, Robert M. Pirsig's Zen and the Art of Motorcycle Maintenance is a powerful, moving, and penetrating examination of how we live . . . and a breathtaking meditation on how to live better. Here is the book that transformed a generation: an unforgettable narration of a summer motorcycle trip across America's Northwest, undertaken by a father and his young son. A story of love and fear -- of growth, discovery, and acceptance -- that becomes a profound personal and philosophical odyssey into life's fundamental questions, this uniquely exhilarating modern classic is both touching and transcendent, resonant with the myriad confusions of existence . . . and the small, essential triumphs that propel us forward.

Goodreads reviews

Every week, for over a year, Alessandro asked his friends, colleagues, and acquaintances that are part of his social networks (Twitter and LinkedIn) the following question:

"What is the book that changed your life? (not novels or religious texts)"

I think it's a wonderful way to connect in a less superficial way and learn a little more about each other. It's also a wonderful way to discover new books worth reading.

This is one of them. The full list is here.
