"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):
Benjamin Franklin is the founding father who winks at us, the one who seems made of flesh rather than marble. In a sweeping narrative that follows Franklin’s life from Boston to Philadelphia to London and Paris and back, Walter Isaacson chronicles the adventures of the runaway apprentice who became, over the course of his eighty-four-year life, America’s best writer, inventor, media baron, scientist, diplomat, and business strategist, as well as one of its most practical and ingenious political leaders. He explores the wit behind Poor Richard’s Almanac and the wisdom behind the Declaration of Independence, the new nation’s alliance with France, the treaty that ended the Revolution, and the compromises that created a near-perfect Constitution.
In this colorful and intimate narrative, Isaacson provides the full sweep of Franklin’s amazing life, showing how he helped to forge the American national identity and why he has a particular resonance in the twenty-first century.
